First Time Owner
[This review was collected as part of a promotion.] Reliable, compact and fast! First time user and we made tailgate coffee every morning on our recent 2 week Montana / Alberta hiking trip. Although I didn’t pack it on trail, it’s small and light so I would not hesitate to do so. Great product and did not disappoint!

Brewing on The Rubicon
[This review was collected as part of a promotion.] I was finally able to take my Jeep out to California to drive the Rubicon Trail. I did a decent amount of research and knew I would be spending 2-3 nights on the trail. Knowing that I knew I would be making coffee on the trail and I also knew that there was a fire ban so I would need to bring my own way of cooking. This was the chose I made. 100% satisfied.

Great product. Although a slight bit heavier then my other set up, the super fast boil time makes it well worth it.

GODSEND when camping with kids!
DO YOU need offgrid coffee available in 5 minutes or less? This is your product. The water boils in less than 2 minutes, then the French press steeps for 3 minutes, press the plunger down and you have 2 delicious cups of coffee. This packs sooo small and light! Even if we weren't offgrid I'd still use this as my camping coffee solution. I am a little confused how the conventional jetboil cooking attachments work with this setup but I'm sure it's easy enough to figure out. VERY happy with this purchase.

Super quick and easy!
Ease of use and speed while on a week long motor camping trip. No issues even in the rain. Igniter lit it every time and the coffee press was a great addition. Glad I made the choice I did in purchasing this!

Extremely easy to use, very stable with the included base, and boils water for my coffee in no time flat. The included press makes brewing my coffee a snap and I can get away from the coffee singles that make flavorless brown water.
