It doesn't work, at least not for me. I was really looking forward to receiving this canister. Talk about "killing two birds with one stone." I bought this to hold fresh coffee beans, and was also delighted with the feature of housing the filters in the same container. The problem is that the canister is almost impossible to comfortably open. I think my hands are normal in size for a woman, but I can't fit my hand around the canister to hold it in order to open the top with the other hand. The "handle" on the top is slippery (as is the stainless steel body),and too short to get a grip on it. It doesn't screw off, but pulls off and since it's airtight this is almost impossible. My fingers kept sliding off-----notice I said fingers and not hand. Handle too small and short for my whole hand. This could have been solved if only they had made a hole in the handle large enough to either insert a hand or at least a few fingers.
No, afraid they'd better go back to the drawing board on this one. Loved the idea, but didn't like the finished product.
