I've boiled water in 15 mph winds outside with this stove with zero issues. It boils water insanely fast and does so with minimal fuel. An 8oz fuel canister will boil more than enough water for a couple over a weekend. The only downside is that it produces a lot of carbon monoxide and is quite dangerous to use even in a tent vestibule, so if there is inclement weather, you will still be required to boil your water outside the tent. Don't try to cook with this stove, it will burn your food so fast even stirring won't help.

This stove is great for 2-3 campers. It's probably too much of a stove for just one person.

Lastly, this stove is very heavy for an ultra light setup. It packs well, an 8oz. canister fits perfectly on top of the burner for storage, and the lid had a nook to lock in the fuel canister so there is no rattling while you're hiking with your pack. Watch out for the pot handle though, it snaps pretty hard and can get your finger if you're not careful.

MSR's Reactor is a dream. Living in Oregon we can have all 4 seasons in 1 day several times a year, and this stove is amazing in all of them. First off carbon monoxide warnings are all over this unit due to the heating elements size which is up to 5 times larger than almost every stove on the market, so the CM output is about 3 times more. Complete windproof design, lower part of the pot is basically sealed with the heat element & the gases are redirected out vents on the lower sides of the pot, its very nice to the eye. 1 liter boil time for me with cold water was around 2 & a half minutes in about 15 mph winds. The unit itself is entirely contained within the pot, and once placed into the pot correctly, the unit is contained & stabilized due to a locking plug in the pots lid that attaches to the top of the propane can which eliminates rattling & loose parts. This setup is about $60 more than most other units but is by far well worth double that, the time it saves you alone is priceless. Side by side to a JetBoil in the same conditions the JetBoil went out over half a dozen times with 6 minutes longer boil time. I would recommend this stove to anybody, camping, hiking or extreme climbing. Also it comes with a small cleaning pad that is pretty thick & instruction books in 8 different languages.

UPDATE: It is September 20 2014 and my Reactor is STILL boiling water and helping me dry out wet clothes. I CANNOT recommend this stove enough. Just steer clear of the coffee press by MSR for it.

I got this stove just before leaving for British Columbia to hike the Rockwall Trail with my best amigos. We have been gathering for an annual backpacking trip for many years now, and we like to make meals that require only hot water: no pots and pans. I have never used a stove that boils water so fast and efficiently as this MSR Reactor. It was a stunning improvement over anything we have used before. The warnings about carbon monoxide are a little creepy, the Reactor apparently cranks out more than most stoves, but we always use our stoves outside so ventilation is no issue. The initial design that won an Editors Choice award from Backpacker magazine had a starter which has sadly been removed, so you need to carry matches or a lighter. But it fires up easily, boils in a few short minutes, and packs up compactly. Watch your fingers with the tension cable that holds the lid in place...none of us escaped a surprising stinging thwack from it!

After about three weeks with this stove and a couple of day hikes, my early take on this stove is that it is all it is advertised to be. It packs well, assembles without any hassle and, as others have posted, boils a litre of water unbelievably fast. On one trip, I set up the stove, lit it and poured my coffee water into the pot. put the lid on the pot, then turned to load and light a pipefull of cherry cavendish. When I turned back, the water was already at a rapid boil (this on a 35dF day, in a swirling 10-14 knot breeze, out in an open space!). My impression is that it is very good at one thing, boiling water. I haven't as yet tried actual cooking in the pot, but even on low setting this would seem to be a challenge due to the sheer amount of heat produced. I'll update my review once I've had the opportunity to try that.
