Almost perfect. cons. heavy. This is like the only cons I found. Hope there will be a Ti version. It can only boil. Since it is designed for high altitude. I can not blame it to much. pros. boil water really really fast. Save gas. Great design such as the handle, the storage system.

very fast
Works great and is easy to set up. In my opinion, works better for boiling water than for actual cooking as it's a little hard to dial it in for simmering. I appreciate the ability to use a canister in cooler/higher altitude situations where I would normally switch over to a white gas stove. As the cannister serves as the base, the setup is a bit less stable than some other stoves. It would also be nice if the stove could be secured to the burner like you can with the Jetboil.

This is a powerful weapon!
This is a powerful weapon! If you want to drink coffee in the outdoor fast, buy reactors will not regret it! Because he can in a short period of about three minutes to boil one liter of water! This is not blowing pieces, I use several reactors and other appliances to do comparison, can be said that the reactor is perfect there! Recommended buy!

Fast and Simple
Easy to use, impressive power and boil time. Great for when you need hot water fast. I have used this at altitude and in very cold weather with no issues. Others (including jet boil lovers) will be jealous. I wish it had an auto-ignitor however. The pot is big enough for it's intended purpose while the whole unit remains at a manageable weight and size.

Fast, Fast, Fast!!
Used last weekend in -16 degree wind chill conditions at 9800 feet. No problem igniting and the design is safe enough that we had our young Scouts do it. Does not have a self igniter, but given that the piezo igniter on one of other stoves did not work in the cold, I am happy to provide my own spark. Easily twice as fast as other stoves in boiling water. I was pleasantly surprised (and thankful), this was as good as advertised. 8 oz fuel canister does fit in pot.
