I had bought one of these that didn't have "teeth" on it. It did not work at all. So I found this one. It has "teeth" on it and works wonderfully! I thought I would have to screw it under a cabinet. So far the two-sided tape is still holding it up quite well though. So that part exceeded my expectations so far. And even if the tape eventually fails, I like this jar opener so much I will just buy some screws to hold it in place.
