I purchased this for my daughter to take to college. It is a nice compact size. She is loving it! She is so glad to have good clean drinking water. I just purchased another one for my other daughter for college next year. I gave Quality 4 stars because the lid doesn't lie flat on the top of the Go Berkey. The black Berkey filter is 1/4 inch taller than the stainless steel container so it sits on top kind of lopsided. That was the only issue we had.
