Query: Sorely disappointed

I really would love to be constructive about the product, but really the only metric it has to pass is "can it open a can?" Unfortunately, it slips off the can after one small turn every single time. It took 10 very frustrating minutes just to get a can of tuna partially open enough to dig out the contents with a spoon. I had an OXO Good Grips can opener before this and it worked flawlessly. I would recommend you stay far away from this one and go with one of the OXO can openers.
