Got 3 of these to salve my recycle conscience and save on cost. I have the smallest of the Keurigs and drink 2 cups a day, so I figured I could keep 2 clean. The good news is that size is perfect, fits beautifully and brew is excellent (just using my adc ground Green Mtn coffee). They work great and are 5 star for that. However, they are made in china of all plastic, including the important hinge top that is the one moving part. I am super careful with this, but it's just plastic, rather flimsy, and there's no way it's going to last repeated openings, which of course are necessary for both filling and cleaning. This would not be a killer if they weren't so relatively expensive. I'm sure it can't have cost the producers even a dollar for these. Either upgrade quality or downgrade price!
