I recently discovered this gizmo and I thought some of you here might find it useful, too. Hubby George doesn't drink coffee anymore - just me. Can't use percolators in the microwave and they are messy to clean up. French presses are, to me, a royal pain to clean, even if I have unlimited water available. This thing just struck me as the perfect camping coffee maker thing. I actually use it in the stick house now, too.
While camping, the hot water can be had from most any source - microwave, stovetop, campfire. You stick a Melitta #2 or #4 filter in it (or a cupcake filter in a pinch), spoon in your coffee, and pour hot water over the coffee. Drip, drip, drip - great tasting cup of coffee in way less than a minute. I use the same filter twice for my two morning cups (just put fresh coffee in over the wet grounds). Clean up, obviously, is a SNAP! I got mine on Amazon for a few bucks.
