This is a cool idea, and the product functions just as it says. Quality is fine, and I didn't experience any problem. If you really want gourmet coffee while your backpacking then I totally recommend this. That being said my experience with it was that it was more of a burden than a luxury. Once you're finished using it you have to use some of your water supply to clean it out, and even then you might end up with some coffee grinds in your dinner. I am just going to stick with Folger's singles (kind of like a tea bag).
