Review on GSI Outdoors - Coffee Rocket Maker, Blue: Brew Fresh Coffee Anywhere! by Faye Wright

Great lightweight coffee maker for camping. Small enough to fit in a 0.78 liter pot so it doesn't take up any extra space in my backpack. The hole in the center of the stainless steel strainer makes it easy to rinse out the coffee when you're done, but there's too much clearance between the hole in the strainer and the stopper at the bottom of the grinder jar to use anything. but a rough cut. I have found that a 7/16 inch ID o-ring placed over the stopper in the grind cup seals it well enough to use medium to fine grinds. That flaw aside, this is the best portable coffee maker I've used for camping.
