I love this puppy, but I lost mine down the San Joaquin, Now I have to get a new one. Easy to Pack, light weight, and simple. Ignore the directions, instead make cowboy coffee in your kettle,cram filter into your Nalgene, filter out the grounds and drink. If you use it in a mug the wings are too narrow and it falls in. Also it displaces too much liquid in your cup to be worthwhile. You can always make strong coffee weaker but it's hard to make weak coffee strong. Trust me.
