The MSR Reactor 2.5L Stove System is one of the fastest and most fuel efficient stoves currently on the market. It is a solid choice for the light hiker all the way to the casual camper. The 2.5 liter pot is ample volume for 4-5 people. On blustery winter hikes you can melt enough snow for your whole crew. Then use it to prepare your signature meal (mine is boiled Spam with bits of Spam wrapper). The heat exchanger completely encloses the radiant burner head and virtually takes the wind out of the equation. This means faster boil times and efficient fuel usage. The stove and fuel both pack into the pot for ultimate convenience.

Rated 5 out of 5 by from The quickest Brew possible I've beenusing reactor stoves for several years as a high altitude guide. Be it camp 4 on Everest, An open bivy on Denali's "football field" or just Tea time on Mt.Vinson's summit day, the reactor stove is the go to when I need to turn snow into something to drink and it is cold and windy. I'll be taking these stoves with me to Kanchengjunga next week where I have no hesitation to rely on them at 28,000'

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from Better imposible! I ve used it in very hard conditions in the south of Argentina, Mendoza. The weather is really cold and windy, but had no problems at all, the best portable stove on the market. Perfect for camping in the highest mountains, and we were three using it.

Rated 5 out of 5 by from 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.

Rated 4 out of 5 by from Burner stop working, pot is fine I have had this Reactor since 2015, love it! Sadly the burner is now slow/dont work and it is not possible to buy a new one without buying a whole set.

Rated 5 out of 5 by from Stove Fits Fine In 1L Pot No idea what some reviewers are talking about but they're giving bad info. The 110g cartridge goes in first upside down followed by the burner upside down to nest into the concave base of the gas cartridge. The control valve needs to be screwed in and laying flat to one side. When the burner is placed in the valve nests into the extra space created by the pour spout and the opposite side sits deeper which accommodate the rubber plug on the lid. It's a snug fit but it can absolutely be done anytime you want without "bending the pot" or otherwise forcing it in.

how long does the fuel last for general camping meals? burn times?

Asked by: CampoNetta
Thanks for the question! The burn time is approximately 80 minutes per 8 oz fuel canister. That is just an approximation as there are many variables to consider - such as outdoor temps, wind, altitude, & flame levels. I hope this gives you a better idea!

How does this stove do at a low simmer?

Asked by: Happy Jack
Hey there Happy Jack, great question! This stove does just as well at lower temps as it does at higher ones, it has a very wide range of adjustability. I hope this helps!

Do you have to keep buying those fuel containers, does it use other types fuel cells 

Asked by: Wondering
Hi there, thanks for the question! This stove is designed to be used with gas fuel canisters, it will be optimized with MSR's IsoPro fuel canisters. I hope this helps!

1. Does the stove have a piezo starter? 2. Is the pot affixed to the stove or can I use other pots, like the ceramic coated non-stick cooking pots MSR sells with the stove? Thanks.

Asked by: Roy22
Hiya Roy22, thanks for your question! This stove is designed to use with compatible Reactor pots and accessories only. You should never use it in any other way than as described in the instructions. Besides, using other pots with this stove would be basically defeat the purpose. You would loose the wind protection and there would be nothing to set the pot on. It does not have a piezo starter. It requires a match or lighter. Hope this helps!
