    Love It.

    • Familiarity:I've put it through the wringer

    This thing is great, very lightweight and brings water to a boil fast! I take this when I am cooking for two people because the size is a little overkill for one person. The design is great and does awesome in the wind. It packs up nicely in to a stuff sack and the canister and stove fits perfectly inside of the pot.

    THE Mountaineering stove

    • Familiarity:I've put it through the wringer

    Melts water incredibly fast, it works much better than my white gas stove in cold temps. You can't regulate temps as well with this, but the efficiency is well worth it for snow based camping or mountaineering where the primary goal is making water from ice and snow. I'll stick with my Dragonfly for actual cooking, but this is the best choice for making a ton of water in a hurry.

    High Altitude Boil Champ

    • Familiarity:I've put it through the wringer

    For boiling water QUICKLY at higher altitudes (9500-15,000 feet) and in the wind, the Reactor is the champ. After several years of use in the Andes of Peru and Ecuador, I remain thrilled with this purchase. The extra effort needed to keep the canister somewhat warmer is a small price compared to the time it takes to prime and wait for a white gas stove. If I was running solo, I'd take another look at JetBoil but for two or more, I'll stick with the Reactor. You can boil, eat and be in the bag before your white gas buddy has warm water. I tried to cook in it once and was a bit frustrated trying to control the output so I stick to its strength - super fast boils.

    Aconcagua Tough!

    • Familiarity:I've put it through the wringer

    Worth $500 when your melting snow at 19000ft in 40 mph winds and still getting the job done. MSR won with this stove for sure! Walked on Jet Boils when I was up there!

    Great Stove

    • Familiarity:I've put it through the wringer

    Ive used this stove in many different situations. Its boils water and melts snow exceptionally fast and its very compact making it easy to carry and store. The only gripe we had with this is when it gets really cold. If your winter camping plan on sleeping with the canisters in your sleeping bag, or having an XGK to heat up water to heat the canister. If it is not warm it does not output the maximum amount of heat and you end up wasting fuel. Overall a very reliable stove just needs some TLC to keep it warm.

    Great Stove

    Yeah, I had never used it in that cold of temps before, missed some beta on that for sure before our trip. Next Year looks like Jetboil is coming out with a stove to match the Reactor but, it puts the canister upside down to make the fuel come out much more efficiently. Sounds interesting, currently they only make it in a 2.5 L pot, waiting for them to come out with a liter option as the 2.5 is a bit big for a 2 person trip.

    Fast

      This stove boils water so fast. It is unbelievable. It is lightweight, and it is compact. I think the msr logo on the burner is a really cool feature, plus it gets a lot of "whoas" at camp. I woke up in the middle of the night once freezing, knowing that if I didnt get warm soon, we were going to have an issue. I took this outside, and had myself 2 boiling hot nalgenes in a matter of minutes. My only gripe is that I wish it had a piezo lighter, so I didn't always have to have matches with me. This stove has saved my butt. Excellent, fast boiling stove.

      Incredible at melting snow

        If you're heading out for some winter camping and need to melt snow. This is the one and only stove you need. Melts snow faster than anything I've seen. It uses a bit more fuel than others, but when you can be done melting snow 15 minutes faster than anyone (or anything) else, it's well worth it. Simmers pretty well and is fairly light.

        Great system

          It all stacks together neatly, which is cool, but the main thing is how amazingly fast it boils water or melts snow. It's incredible. MSR also makes a separate piezo igniter that's pretty neat.

          I usually figure 1 large fuel canister for 2 people for 2 days.

          The downsides are that fuel is less flexible than other stoves such as my msr dragonfly which I've run on various gasoline in foreign countries.. You have to have the canisters. But this stove is way better for backpacking in the cold.

          If its very cold though you'll need to keep a canister in your jacket/sleeping bag for it to flow correctly. My last "gripe" is that there's no way to recycle the spent canisters. It'd be great if MSR had collections at various retail stores for the used canisters.

          Overall the best stove I've seen for everything except places where you can't buy or carry enough fuel.

          Great system

          The canisters are definitely recyclable. Vent the canister 100%, poke a hole or two in it, throw it in the recycle bin. Jetboil makes an invaluable and safe tool to accomplish this called the Crunchit.

          http://www.backcountry.com/jetboil-crunchit-fuel-canister-recycling-tool?ti=U2VhcmNoIFJlc3VsdHM6Y3J1bmNoaXQ6MToxOmNydW5jaGl0

          Sure as hell beats the way I use to do it. Vent remaining gas for a day, then poke holes with a hammer and punch.

          Hot

          • Familiarity:I've put it through the wringer

          Awesome. You hear about people who hate any stove that uses these fuel canisters.. For one or two people this stove pot system rocks. I have been looking at getting the larger pot sold separately. I just feel that once you start getting into needing a larger pot you should move into a fuel bottle stove system and spread the load amongst those in the party.

          Reactor Stove

          • Familiarity:I've put it through the wringer

          Pretty cool stove! Hard to light in high wind but once it catches its definitely not going out even if you spill an entire pot of water on it. Obviously it boils fast. It even can be held if you are using it somewhere not recommended like in the tent. I do wish the pot would attach to prevent the aforementioned spilling but once that happens you learn quick to hold on tight and it hasn't been a problem since. The included pot is perfect for two people and will work for three if you dont have to melt much water. Three people in the winter might want a bigger pot. I like being able to store everything (including fuel) in the pot. It packs nicely into the bag and protects the stove well.

          Any idea how the propane / butane canisters can be safely emptied / disposed of if they are over the 3 year shelf life?

          Best Answer

          We strapped an M80 to one. It was a loud bang, then a big white cloud sprayed out followed by a big fireball. It was fairly cool but not the giant Hollywood explosion we were hoping for .

          I have an older Coleman lp stove for car camping but want something that is lightweight and solid construction where I can boil water, make water based food, and use for general food making. In talking with others msr makes the best lightweight stoves but don't know which is the best and most versatile. Any recommendations? My use is car camping or short hikes to camping areas

          You could get away with much less stove - a pocket rocket or an older version of a liquid gas stove. This stove is the best of the best - you will enjoy it and it will last a long time. Check out a jetboil as well - a little lighter and works very well but not as well in the cold. Canister stoves in general are somewhat sensitive to the cold.

          Best Answer

          For a wide use of needs (car camping, actual cooking, short backpacking, etc.) it's tough to beat the MSR Windpro II. It's a bit more expensive than some stoves, but cheaper than the Reactor. And, it has a huge range of adjustability, can be used with a windscreen and allows you to invert the canister to feed it the fuel in a liquid form if the temps get too low.



          I have the Reactor and the Windpro. While the Reactor rocks for super-fast water boiling in a number of conditions, I think the WindPro is a more solid, all-around choice.

          Can't decide whether to get the Jetboil PCS, Primus EtaPower or this, please help!

          Stove being used between two people, mainly for boiling water to cook dehydrated foods and making powdered drinks.

          The Reactor is simply one of the best stoves out there. If I were planning more week long, high altitude, extreme temp excursions, I would have went with the MSR Reactor. However, when I was in your situation, I went with the Jetboil PCS, because over the past few years 90% of my trips were weekender's, mild climates, and simple dehydrated meals with instant coffee. For this, I believe the Jetboil PCS is the best choice. If this sounds like you, save the $60.

          How efficient is this stove when using...

          How efficient is this stove when using other pots/pans besides the one it comes with?

          Best Answer

          Unfortunately, the Reactor doesn't work with other pots/pans. This is due to the convex structure of the burner (not a flat surface to put a pan on but domed). The reason for this is because the engineers wanted to create as efficient a stove as possible and in order to do this they had to make the stove and pot be as one.

          It should be noted that this stove is hot! Therefore, in my opinion, it is not a good stove to use a frypan on, even if one existed that would fit the burner. A new 2.5 liter pot (sold separately) along with the 1 liter pot are the only two recommended for this stove.

          The Reactor's strength is speed in boiling water and efficiency. It isn't very good at simmering nor in performing other types of methods used in cooking gourmet meals. It's best used if you need boiling water for already-prepared meals, or for melting snow. It should also be said that due to it's ability to fend of wind and suck up as much heat as possible makes the Reactor a true 4-season stove. That's rare to say about a canister stove.

          I would recommend the MSR WindPro Stove for use with any type of pot/pan available. It's MSR's best canister gourmet-cooking stove.

          What is the shelf-life of a cannister of...

          What is the shelf-life of a cannister of MSR IsoPro?

          We've actually been told that, to be safe, it is recommended to only store your canister fuel up to 3 years. The reason for this is that the Lindal Valve used on canisters, which allows the stove to be removed from the canister and then re-inserted, has a rubber O-ring that can deteriorate over time. Because the fuel inside the canister is highly pressurized and flammable, the O-ring can fail resulting in fuel leakage. Best case scenario is that the vapor will leak out resulting in an empty fuel canister. Worst case is possible ignition resulting in a fire hazard. The likely hood of this is rare, but possible. Fuel leakage will most likely not happen in three years, but to be safe, the time period of 3 years has been agreed upon by those who manufacturer the Lindal Valve. In other words, you take a risk of leaking fuel after a 3 year period.

          Best Answer

          Thanks Jason. I know the time is probably going to be longer, but the official word is a good reference point. We have a stash of these for our earthquake supplies. We're under 3 years on those, so we'll start rotating them with replacements when the prescribed time comes.

          ok, so what fuel can this stove use besides the MSR isopro?

          All the ones listed by Phil will work well, especially in general 3-season use. If you plan on taking it on the cold (25 deg F or lower), choosing a higher-quality brand like MSR will mean better performance. You can read more here:

          http://adventuresinstoving.blogspot.com/2011/11/whats-best-brand-of-gas-for-cold.html

          Yeah, Brian is right. The Isopro canisters always seem to give us the best flame quality and burn time. With the others, we get a lot of spitting and have to constantly adjust the valve to come back to that nice, even blue flame. We've tried pretty much all the others to see how they perform and to save a buck or two, but we always come back.

          I am looking for a stove that is small,...

          I am looking for a stove that is small, lightweight and boils water quickly. It needs to be easy to use and fit in a kayak. It will be used on rivers in Utah, Colorado, Wyoming and Montana, so altitude, the possibility of getting wet and wind (which I seem to attract) are all concerns. The Jet Boil, MSR Pocket Rocket and and MSR Reactor all seem like good choices.

          What does this include out of box as ordered...

          What does this include out of box as ordered here? Is it possible to use fuel bottles on this other than 8oz?

          It includes the stove, pot and lid. Fuel canisters are sold separately. You can use any size fuel canister (as long as it has the Lindal valve - no white gas or other fuel types will work). The larger canisters (8oz) do tend to provide a more stable base for the setup, though.

          Can you tell me if it's possible to use...

          Can you tell me if it's possible to use other brand fuel cannisters with it (such as Snow Peak, Coleman, etc)?

          MSR's IsoPro is an 80/20 blend of Isobutane and Propane. Snow peak and Jetboil canisters are also an Isobutane/propane mix. Some others probably are as well. I'm not sure what is in coleman's canisters, although if you can get your hands on one it should say. Anything that's an Isobutane/propane mix should work, although it may not burn as clean or as efficiently as MSRs canisters, since their stoves are designed specifically for them (the 80/20 mix).

          Certainly MSR would like for you to use their fuel however any eight ounce, Lindal valve canister will work equally as well. To the best of my knowledge, Coleman is the only fuel that doesn't use isobutane in their mix.

          Best Answer

          You can safely use any canister (Brunton, Primus, Jet Boil) other than Gaz and Snow Peak on the pressurized MSR stoves. Gaz will not fit at all (different connection), and Snow Peak will fit most of the time (ever-so-slightly different connection), but I have seen Snow Peak canisters leak while on other brand stoves, and that can lead to a scary situation if your stove it lit!

          I'm very surprised to hear about someone having problems with Snow Peak canisters. I've found them to be both very reliable & completely adaptable to all other stoves using that type of fuel canister. I wonder if there could have been some other underlying problem?

          I have used a jetboil in the past, and...

          I have used a jetboil in the past, and really like it. I then went the ultrlight route with a snow peak gigapower, and ti pot setup. I found the weight savings were negated by the extra fuel needed to be carried due to the poor fuel efficiency. I am now interested in purchasing either a reactor or jetboil again. I get how much better the reactor is, but the things I don't like is you don't get any measurement marks other than .5, 1, and 1.5 liters, and I would have to carry a seperate mug for hot drinks. I know it doesn't sound like much, but every ounce counts. I don't want to have to carry extra gear just to make the heavier reactor do everything I need. So my question is, does the reactors advantages over the jetboil enough to offset the added weight and gear. Keep in mind I backpack mostly in the southern appalachian mountains in all seasons, but temps rairly get bellow zero. When I do travel west to backpack it is always in summer.

          Best Answer

          It sounds like the jetboil might be a better option for you. HOWEVER - although the MSR is heavier, it will perform better at altitude (if this is even a concern for you) and I think the MSR, due to the size of its pot, would boil more water more efficiently (possible fuel savings) for 2 or more people. Also, although the jetboil has an auto start - it will inevitably fail (and probably THE reason MSR doesn't use them). If you do take a mug with the MSR, it could easily solve you're measurement problem as well!

          I'm conserend with CO-2 in side the tent

          Best Answer

          Though this stove looks like it would work as a tent heater, DON'T DO IT! Most would set the heat to low (this stove burns very hot) which is the worst possible setting because this is where it puts out the most carbon monoxide (carbon monoxide displaces oxygen in the lungs which results in suffocation). The reason is the flame has to get above 3,000 degrees F in order for the heat to bond carbon molecules creating carbon dioxide (harmless gas). Thus, on LOW, the Reactor puts out enough carbon monoxide to be worrisome and is seriously not recommended. Even inside a vestibule you have to make sure you have adequate through ventilation. For the record, MSR strongly recommends not using the Reactor inside an enclosure. It is up to you if you wish to follow this advice or not. If you do, use on HIGH as this will put off more carbon dioxide and less carbon monoxide.

          No one is going to recommend cooking inside the tent. But real life (weather conditions come to mind) can be quite different then what is written in the user manuals. If you do decide to use it inside your tent then do so sitting upright with all the vents maybe even door open. Ventilation is key when cooking inside your tent!

          I wonder why MSR did not include auto...

          I wonder why MSR did not include auto ignition. That is one sweet thing about the Jet Boil. Getting a bic child proof lighter to work on Rainier in the gusty winds was next to impossible, but the jet boil came through. What is it going to be like trying to light this?

          Best Answer

          Fortunately there are other methods of lighting a stove without a lighter. I would recommend windproof and waterproof matches (REI branded have worked well for me). I also like the spark lighters like Light My Fire. With the Reactor, all you need is a spark.

          The reason why MSR didn't include a auto ignition is for a couple of reasons. One, it simply ISN'T reliable. If the ignitor gets wet, it won't work. They easily break as well. A major worry of MSR's is that people will look to it as their sole way of lighting the stove inwhich it will inevitably fail.

          The second reason why MSR won't put it on their stove is that they eventually wear out. Because it would be permanent component on the stove, the thought of it wearing out in a few years doesn't jive with their idea of quality. MSR is working hard on other auto ignition technologies and may have something in the future. However, it is a far better idea and much more reliable to depend on an outside source for ignition.

          What is up with that stupid sticker???

          Like Kurt Z mentioned in his review ... there is a warning sticker on the pot, containing the same warning information that is attached to the burner (the actual combustion device!) that is impossible to remove without toxic solvents. My first experience with a $160 stove ruined by a $0.25 sticker. I really hope Cascade Designs gets this one sorted out - it pissed the hell out of me, and maybe others?

          Haven't really used much yet but is very impressive on first use. The first time you see the stove primed after warmup is incredible and leads you to a "wow, that is badass" moment.

          I contacted MSR because I had the same question and here was there answer

          We had to elect a “permanent” adhesive for the warning label to satisfy a variety of requirements, many of which are specific to an integrated stove system, so the label is not intended to be removed. The label itself is a durable, waterproof stock that is very heat- and chemical-resistant, and was tested to withstand a lot of abuse. Unfortunately, we are stuck with the label as it is… One of the most stringent regulatory agencies that we deal with is CSA (the Canadian Standards Organization). They explicitly require permanent labeling for certain things. Although the standard was not re-written with the advent of the integrated stove system, we try to be conservative in our interpretation and in our measures to comply.

          Thanks Jason for your significant insight. Reactor seems technically better but dont like that only works with its pot. Being more specifically I like convenience and ease and would like to use for short backpacking trips(not winter) and camping with girlfriend. Which system (of all) do u recommend.

          Best Answer

          This pot is probably overkill for what you want. This pot is designed to ONLY boil water which limits your options. If you want a more versatile system check out something else.

          If you want ease of use, check out canister stoves such as the MSR WindPro or Pocket rocket.

          If you want something cheaper in the long term, get a liquid fuel stove such as the Wisperlite.

          If you want to cook gourmet meals in the back country and need to regulate heat get the Dragonfly.

          Good Luck

          Short backpacking trips, ease of use, and girlfriend?

          buy a remote canister stove, msr wind pro, snow peak bf, brunton vesta, optimus stella, etc.

          Don't get me wrong, I like my liquid fuel stove and my ultralight canister top stove, but there is a time and place for everything, and if I owned one stove it would be a remote canister with a fuel preheat coil. Funny that its the one kind I dont have.

          oh, I'd buy the snow peak bf, large burner if it was my money

          For convenience and ease of use go with the MSR Pocket Rocket. It is a completely reliable 3.5 season stove that is ideal for short or long backpacking trips. It integrates very well with the GSI Dualist cook set system for a very compact and easy to use set up. The entire cost of everything should come in at well under $100 if you shop around.

          Need Expert advice who has experience with Reactor and Jetboil. Trying to decide between the two. Thanks, Steve

          Best Answer

          This is a pretty general question, but I will do my best:-). There are several differences between both these stoves, most noticeably the stove itself. The Jetboil's stove is nothing more than a traditional small canister stove. It is very similar to the Alpine Lite Stove made by Primus. The mere fact that it uses a heat sink on the pot and has incorporated this stove into a system makes it different than other canister stoves. However, it is not 100% wind resistant (needs both primary and secondary air), and it doesn't have anything to regulate the pressure being generated by the canster (meaning it's performance is completely dependent on the weather and amount of fuel in the cansiter). The Jetboil isn't very light either when compared to other sit-on-top canister stoves (weighs in at about 15 oz.). I would recommend the Jetboil for those who want a fairly small, compact stove/pot system who primarily boil water. It does so fairly efficiently and quickly when compared to other stand-alone canister stoves.

          The Reactor is entirely different. The only similarity between the Jetboil is that it uses a heat sink on the pot and is also a stove/pot system (meaning no other pot will work on the Reactor other than the included pot). The Reactor's stove is truly innovative in that it uses a pressure regulator (meaning it only needs about 12 psi to obtain optimum heat output compared to 65 psi for every other canister stove including Jetboil). It also needs just primary air (primary air, located below the stove's burner head, is where 60% of the stoves combustion is generated...secondary air, located between the stove's burner head and the bottom of the pot, is where 40% of the stove's combustion occurs...block either of these off and the flame will go out). The Reactor's need for only primary air makes it 100% windproof by allowing the pot to rest directly on the burner head thus protecting the heat output. The Reactor is the only stove that will give you consistent 3 to 3:30 minute boil times per liter in any condition above about 10 degrees. The pot is one of the most innovative pots for heat distribution and efficiency based on its laser-welded heatsink and 'shroud' (the shroud captures any heated air and traps it for a moment to help improve efficiency...the holes around the circumference of the pot allows this hot air to escape-it's also laser-welded on). Just to be clear, the pot has been updated and is now lighter (about 10oz.). The stove weighs in at about 6.5oz. making the complete unit (without fuel) weigh in at about 16.5 oz.

          If your interested in sheer performance and efficiency, the Reactor is the stove. If you want a smaller stove system and are willing to give up some performance and efficiency, and plan to only use it for solo use, the Jetboil might be the better option. Remember, the Reactor can boil a liter at a time whereas the Jetboil can only boil 2 cups. Hope this helps....

          Does anyone know why the price of the stove...

          Does anyone know why the price of the stove has increased from last year? Its about a 13% increase?? Gear people from Backcountry only have the hypothesis that cost of materials might have gone up? The stove doesn't look like it has changed in any way from last year's version.

          The way you can tell whether you have the old pot vs. the new one is how the shroud is welded on. If you notice 6-8 tac welds, then it is the old pot. However, if you see a continuous, very small weld around the circumference of the pot, then it is the new one. Another way to determine old vs. new is the heatsink which will be welded on on the new pot and forged on the old. You're pretty safe in getting a new stove/pot since the last old stove to go out was last year (2008)...

          I'm looking to get into alpine style...

          I'm looking to get into alpine style climbing, is canister or liquid fuel the why to go? Which does better at altitude and in the cold? I heard the liquid fuel does better in the cold because generally speaking the fuel does not freeze. Is this true? What are the pros and cons of each fuel system?

          Best Answer

          Liquid fuel is much better in the cold because it NEVER freezes. White gas freezes at minus 120-something, I believe. Plus you regulate your own pressure with a liquid fuel stove. Canisters do terribly in cold temperatures, but they are lighter and don't take as long to prime. All in all though, the extra time and weight is better than not having hot food, so go with a liquid fuel stove.-------------The biggest benefit for liquid fuel in cold temperature is that you control the pressure in the fuel bottle. That's it's real advantage. Canisters are dependent on the pressure inside. The great thing about the Reactor is it will work at 0degrees and above. For a canister stove to work at this low of temp is amazing! I've used it several times this winter to melt snow and have been very pleased. It is the best performing canister stove on the market.If you think that you will be in temps below zero you will be better served with a liquid fuel stove.

          So what is the consensus---Reactor or JetBoil?

          Reactor all the way. There are 3 big advantages to the reactor over the Jet Boil.1. Pressure Regulation- This stove has a pressure regulator that basically allows the stove to use all the fuel in the can and no difference in performance no matter how little fuel is in the can. At the last 4% of fuel the stove performance goes to crap. With a jetboil once you get to the half way point the performance begins to drop significantly2. The stove is wind proof- This is accomplished because the stove is a radiant burner rather then a convective burner stove. This allows the pot to sit almost directly on the burner. There is no heat being lost by the wind coming by and blowing the convective gases away.3. Cold Temp Performance- This is combination of the pressure regulator and the pot sitting directly on the burner. The stove will boil a liter of water in about 3 mins no matter how much wind, how cold it is, or the altitude. As long is the fuel can is not gelled up. People who use this stove a lot will tell you that this is the best winter canister stove on the market.

          REACTOR !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! first of all, the curren jetboil has currently been reccalled, because the simmer thingy broke, whose to say that the next step is that they start blowing up, reactor boils water faster, the reactor directs the fuel directly to the stove, so no fuel is lost, and at the very last bit, then the stove turns bad, but with the jetboil, when like 60% is lost, the stove turns bad, and the reactor pot sits directly on top of the stove, so no heat is ever lost, while the jetboil requires a screen, the reactor dosn't. and if you ask any other backcountry expert, they will tell you that the reactor is THE BEST STOVE EVER !!!!!!!!!!!!!

          I own the Reactor stove by MSR and LOVE it. My only problem has been it's preformance in single digit temps. Does anyone know a trick that might help keep the fuel canister from freezing WHILE I am cooking on it?

          Best Answer

          One thing that might work is sticking the canister in a pot with enough water to cover the canister above the level of the fuel while it's being used (obviously I wouldn't let the water get to close to the Lindal Valve (where the stove connects to the canister)). This will help keep the temp of the fuel up enough as to not effect the vapor output. It's NOT recommended that you use your hands to warm it up. This might cause skin damage. Single digits is about the limit of where the Reactor will work. Most canister stoves won't even function at this temp.
