I bought the Jetboil system this last year, and had the chance to finally put it to the test in the Eastern Sierra Nevadas this last week. The wife and I went backpacking through the Ansel Adams Wilderness on the John Muir trail for four days, and really put it through the rigors of outdoor life. I'd recommend this product to anyone serious about saving space for camping and/or backpacking. 2 cups of boiling water in less than 2 minutes. Perfect for Mountainhouse meals, perfect for a nice tall cup of coffee or tea, perfect to treat creek water in a pinch. This little dandy all fits itself into the cup, fuel and all. We boiled about 22 cups of water on one fuel canister, which was way more than I originally anticipated. Seriously guys, great product and worth the $100 or so you'll spend on it. Just thought I'd give you guys a heads up!
