MSR Reactor Stove Systemis rated4.5556out of5by9.
Rated4out of5byfromBest backpacking stove on the marketThis this is awesome. It's light, easy to clean and boils water ridiculously quick. My only issue is that when I first got it there weren't many attachments (i.e. frying pan, large pot etc) which was okay for backpacking but wasn't handy for car camp trips. Now that there are attachments they are too expensive. Otherwise this stove is worth the money.

Rated5out of5byfromThis Thing Is A RocketSeriously, from outer space. I have never seen anything boil water so quickly. Using cold tap water the stove boiled 1L (max fill) of cold tap water in 3:45. That makes it almost twice as fast as my Snow Peak GigaPower with MSR's TrailLite Duo set. Just incredible. Only three complaints: 1) I wish they made a titanium version, to cut down weight a little. They have clearly gone to great effort to keep it light, and I suppose it's pretty expensive already, but I'd have paid another $50 to save 3-4 oz. 2) The coffee press for my TrailLite Duo set doesn't fit the Reactor 1.7L, which is too bad. It would be nice to carry one press that fits both of them. I guess it's more practical to just buy a Reactor press kit and bring that along, since the reactor is way better at boiling water. 3) MSR clearly knows how to do ceramic coatings. If they'd put one on this stove then I could use it for spaghetti or ramen without worry. As is, the aluminum will be a pain to clean.

Rated5out of5byfromHeavy but worth it!Been out camping with friends for a while. Used this a few times. The reactor can boil water extremely fast. I had to boil water for a few MRE's and I would have to say I am very happy with this. I tried lowering the heat to cook some fried rice and it worked good for the most part. Controlling the heat was diffcult. Theres OFF, and a millimeter turn to simmer heat, then the rest is just full-blast afterburner! At 1.3 oz, this is good for couple camping. For solo, might be better off with the 1.0, but I cannot speak for that stove system. That said, it does what its supposed to do. Cant complain.

Rated4out of5byfromFast heating stove great fuel economyI love this stove. I've used it on two backpacks, a 4 day and a five day. The 4 oz canister lasted 4 days with fuel to spare and the 8 oz canister had about a third of its fuel left after 5 days with cooking between 11,400 and 10,800 feet in windy, cool, wet weather. The stove and canister fit nicely in the integrated pot (I got the 1.5 L pot) with room to spare for matches and spork. When you buy this stove you need to understand that this is for boiling water quickly so freeze dried food can be re-hydrated. There is no simmer. I put this down as a con even though I knew when I bought it is was just a quick boiler. The only real con is that it does not have a lighting mechanism built in. I had a hard time lighting the stove in wind. I'm hoping to find out the trick to this.

Rated4out of5byfromFreak failure? I'm betting on it.I first bought this stove in 2009 when I wanted to move from liquid fuel to gas. I was thrilled with it, most especially the speed at which it brought water to a boil. Used in on many backpacking trips including the JMT (John Muir Trail). While it is a little over the edge (in size) for solo backpacking, I continued to use it even on solo trips because I loved the reliability, speed, and ease of use. That changed on my last trip, a two week trip through southern Utah's canyons. On my second day out my stove refused to light. I had just weathered a 16 hour rain/hail/and snowstorm. My stove was outside, but protected under my backpack cover. Dried it out, etc. but it never recovered. MSR gives a lifetime warranty so just to show you how much I like the stove, and consider it's failure just a freak thing, given the choice between a full refund or a new stove I took the new stove. Adventures await, we'll see how it performs!

Rated5out of5byfromSweetness in Can FormI have used the li'l can that could extensively-- backpacking in a wide range of seasons and climates, canoe camping, day hikes, cross country skiing and when ice fishing. Durable product that does exactly what it means to-- boils water "like, super fast!" It is well built and packs up in a nice fashion to help conserve space. Google MSR Reactor recipes and you'll find some fast, easy and good-tasting ideas. My creation: 1 packet instant potatoes, 1 packet Knorr noodles, a little razzle dazzle and > you've a tasty trail treat. Thank you, Science, for helping me to better enjoy loving Nature.

Rated5out of5byfromA joy to useI originally reviewed the Reactor for MSR prior to its distribution and have now used it several years. it has never failed to impress me. I have not used it in arctic conditions but seemeingly it excels in everything short of that. Nothing like it has come out since nor is anything on the horizon it appears. Great job MSR!!

Rated5out of5byfromAll Hail The Mighty Reactor!Went on a 5 day backpacking trip last year to the Grand Canyon. 5 men, over 40 miles of backpacking on some of the hardest trails I have ever experienced. Hit camp, break packs open, rig tents, boil water, eat, sleep, wake, coffee, breakfast, break camp and go again. Jim had a Whisper Light, and myself, the new Reactor. Every evening and morning, I would have boiling water ready to go in less than 4 minutes. Their stove was always, with out fail, 5 minutes behind. All were stunned at the speed of this nuclear fission device. It even glows with letters MSR on the actual burner. Sexy does not come close. Reliable, light and just plain rocks. No fuss, no mess, stows quickly and easily. By day 3 all had coffee cups at the ready and lined up for hot water long before the Whisper Light even warmed up. MSR does it again.
