The five main things I like about this stove is:
1. 12,000 BTU's,
2. The way it folds down & fits into the bottom of your fuel canister,
3. Very lightweight,
4. Constructed of high quality components for durability & longevity,
5. Fuel efficient. Uses 5g of fuel to bring 8oz of water to boil.
If you're a stove nut like me, this is a must have for your collection.

I got this stove last spring, used it quite a bit this year, and so far i don't have any complaints. If you know you want a Compressed Butane Canister stove i would definitely check this one out. Its super affordable, and like some of the other posts have already mentioned it puts out a large sized cookable flame for the stove's small size. It has pretty good heat control as well, especially compared to some of the stoves my buddies use. One thing to remember about the compressed gas it uses, if the temps at night get pretty cold you probably need to sleep with your canister in your bag or it will be difficult to get a consistent flame in the morning.

Almost disappears in your pack it is so small, my only complaint is the extending arms got very stiff after the first use.

I love this stove. very light very compact. I fit it inside my msr titan cup along with my brunton spork and a lighter.

Just got this stove and have yet to field test it but so far I think it will do. Pros: tiny, you can fit this thing just about anywhere, doesn't quite fit under the 220 as well as I would like and will probly just thow it on top of the canister in my pot. The flame adjustment is great. Unlike others who say it is hard to adjust I would disagree, you can easily get this thing to simmer. Cons: no need to wast the time and ounces with the included carry case, top seems to be a bit wobbly and unstable, something I may be able to remedy with a quick tightening or whatnot, certainly not something I would leave unattended. Overall I am pretty happy with it. I'm guessing it will serve its purpose and be a part of my gear for a long time to come.

This stove works great. Folds down so small and fits under the canister inside my cookset (Optimus Weekendeder). The "stuff sack" it comes with does not nestle inside my cookset, so I just keep it form bouncing around with a microfiber camp towel. It will boil a liter of water in 3-4 minutes, and I got 6 boils out of a 220g canister in moderate temperature, 60F, with little wind. I can blow it out myself, so I would recommend a wind screen if you will be relying on this stove for all your cooking. Temperature control works well for me and I am able to cook fresh eggs for breakfast without any burning. The folding arms do tend to become harder to open/close after their slight warping during normal use, but I actually prefer this since they wouldn't stay closed during transportation before it was used. The Optimus Crux does boil water faster than the Frigidaire appliance I have sitting in my kitchen at home. I highly recommend this stove.

we really love this little stove. it heats up really fast and did the trick just right! it doesn't hold a ton of weight, but that is to be expected since it's so small.

Sure is light and nifty, but the folding burner does not lock properly and I spilled a liter of boiling water the first time I used it. No harm done, but if you do this on a small bivvy ledge you could end up with it in your lap! Too bad, because its bad engineering, not a bad concept. The valve is sooooper touchy! It seemed like unless you had it cranked up like a Saturn V (am I dating myself?) you could not touch the valve without the stove flaming out instantly. Don't know what the cause of that is, but it's not something that happens on the any of the other half dozen stoves I own. I took it back to MEC and they gave me refund! Optimus needs to fix the wobble, or they'll have liability issues!
