I busted this out on a recent camping adventure and was extremely pleased with the results. It's really easy to use. There are little dashes inside the container showing lines for filling for either 4 or 6 cups at a time. The coffee was great though slightly on the weak side. I attributed this to the fact that I didn't let it do its things for quite long enough. Washing this beast is a breeze. All the pieces come apart for extremely easy cleaning and it is dishwasher safe which is always nice.
