The MSR Reactor 1.7L Stove System is an innovative, fast-boiling, fuel-efficient, windproof cooking system. Ultra-efficient, the radiant-heated Reactor 1.7L Stove System boils a liter of water in just 3 minutes! This ground-breaking stove is coupled with an integrated 1.7 liter cooking pot for use as a compact unit.

The Reactor 1.7L Stove System's state-of-the-art burner utilizes two modes of heat transfer, convective and radiant, to ensure that maximum performance is achieved in varying conditions. The burner is enclosed in a heat exchanger, protecting it fully from the wind and positioning heat directly where you need it, underneath your cooking pot. As a result, heat loss is minimal and cooking time is greatly reduced. An internal pressure regulator equalizes fuel pressure and guarantees a consistent heat output in all temperatures. This frees you from worrying about poor performance in cold weather and makes certain that you are best able to take advantage of any and all fuel available in your fuel canister.

The 1.7 liter aluminum cooking pot is designed to work hand-in-hand with the stove itself. It is compact and lightweight enough for solo trips, but large enough to boil water and cook for up to 3 people. The pot is also designed to hold and carry the entire Reactor 1.7L Stove System as a single, compact unit. Together, the stove and cooking pot weigh a mere 17.5 ounces.

The MSR Reactor 1.7L Stove System utilizes 4 ounce or 8 ounce canisters of MSR IsoPro fuel (sold separately).

Likes: The MSR Reactor Stove System is everything its advertised to be! It really does boil 1 liter of water in just 3 minutes. then the stove cools down quickly after use. Worth the price!

Dislikes: NONE

Reviewed by Mark S. - May 6, 2009

Likes: This thing is awesome! It boils water as quickly as advertised and is lightweight. It is very frugal on fuel, meaning less is needed for the trip. Most other stoves would require twice the fuel. It couldn't be simpler to light. It all packs into the pot making it easy to pack. It uses the same treaded propane/butane cannisters as other manufacturers. Great for small group, lightweight hiking.

Dislikes: The pot is part of the stove and it heats fast. This makes it great for boiling water, but will burn oatmeal or anything that needs to slow cook. It is primarily for boiling water for freeze-dried food, soup or tea. It does not have its own sparker, you must supply your own or use a match.
