I hvebeen using a press for many years and have several of the models mentioned above.For camping, this is the only one I take any longer. It is perfect.
I admire those using a french press, as I use to do that myself. It's living big in the woods! But I've been trying to make cooking (and cleaning) as easy as possible while camping, so I too have gone to the Starbucks instant coffee. It's not as good, but with half-and-half it's good enough. That way there is no press or coffee grounds to clean up.
