Melt snow with lightning speed and efficiency.

Whip up dinner for a group or melt a heap of snow fast when you're cooking with the MSR Reactor 2.5L Stove System. MSR's engineers gave this system a large, group-friendly pot and went to great lengths to make the burner system utterly reliable and supremely efficient. The enclosed burner shrugs off winds up to 12 miles per hour, the fuel-pressure regulation system maximizes the life of every fuel canister, and the integrated stove-and-pot design makes for rock-solid stability when cooking and easy storage when it's time to move up to the next camp. Being the largest system in MSR's Reactor line, this stove system is ideal for large groups traveling in the alpine and will boil enough water to heat about five freeze-dried meals at once.

Great for backpacking

I purchased this product in Korea and am extremely satisfied with its performance. It's incredibly lightweight, durable, and boils water rapidly. During my hiking trips in Korea, all of my cousins were impressed by its capabilities. This product is like magic, enabling me to prepare kimchi stew or budae stew within 5 minutes, even in the cold mountains. Korean culture includes enjoying grilled bbq even in remote locations, so in my opinion having a lightweight and portable grill that complements the reactor would be fantastic. Thank you for consistently producing outstanding products.

Can't be repaired

I love this cooking system. However, on a 10 day sea kayaking trip in SE Alaska my Reactor failed without explanation. It simply wouldn't pass fuel through. No field repair was possible. When I called MSR I was told "this happens sometimes" and was reminded that I could always soak my food and eat it cold. I had to purchase a new cooking unit. I continue to use the system because it works so well but will never again take it on an extended trip without a backup system.

Group backpacking.

We use these on all of our group backpacking trips for boiling water for our boil in the bag meals. Efficient and fast! We usually carry two for a group of 10-12, but could definitely manage with one.

Hot water on demand

Whoever said "a watched pot never boils" didn't have a Reactor. One of my most satisfying purchases ever.

Still the best in my opinion

Still the Gold Standard for speed to melt snow and bring it to a boil, even @ high altitude and using the least fuel. It can be outside the tent in windy conditions at low temps with no additional windscreen and still deliver performance that beats all other competitors. I have used a Reactor stove since they first came out and now I have a Tote bin full of other brand stoves aaccumulated over 30 years that go unused

1.0L version needs a nesting bowl

I really like the Reactor system. Super fast and efficient. The 1.7L nests nicely with the Deep Dish bowl. This is great when melting snow because you can put the canister in water and keep the fuel from freezing. The 1.0L needs a similar (smaller) nesting bowl! I would love it if MSR made a Deep Dish cup/bowl that nested on the bottom in the same way as the 1.7L does. Please, MSR, if you’re listening, make a Deep Dish cup/bowl for the 1.0L Reactor!

Bomb Proof

I have owned the Reactor since 2010 and used it as a 2-person stove to hiked the PCT, Arizona trail, trips to Alaska in all types of weather conditions and never a problem, heats so fast you cannot turn your back and found 8 oz fuel can do 5 days hot meals breakfast and dinner for two. I still own the original MSR...just can't part with its many decades of adventure memories. Will be rowing from Seattle to Alaska in May 2022 with our Reactor!

amazing stove

I have used this stove for multiple paddle camping trips, hiking, car camping, and even just an outing to the local parks. It's reliable, efficient, gas saving, and burns water fast in any situation I have faced so far. The speed it boils water is unparalleled. I'm buying a delux stove for other cooking purposes.
