Input:
Bought this for our small caf a few years ago, and it made opening multiple cans of tuna about 90% faster.  It still works great, so I just bought one for the house.  Love it - super smooth and easy to use.  I've tried electric can openers, but have never found one I liked.  This is what we'll use from now on.
