When I got this container, I had a problem. I like to grind my coffee from whole bean, but finding a good, air-tight container was difficult. Air-tight is important for this role because flavor goes downhill the longer the ground coffee is exposed to air. 

Seeing this container from OXO, I decided it looked pretty good for this role. Once I got it, and experienced the high-tech and convenient air-tight sealing mechanism, I was sold! It's the perfect size for holding the ground coffee (which I grind in small batches, and keeps it in an air-tight flavor seal. Mighty good, OXO! [This review was collected as part of a promotion.]
