This is a very nice reusable K-Cup that I've been using for a while now. I keep it at work with my K-Cup machine there. I think it's great to be able to use my own coffee with it and it saves me a ton of money. The lid closes with a nice seal and I never have to worry about any leaking or coffee grounds getting loose. It's so easy to wash it out and use again.
