Query: Slips off cans, does not work well

Notice how many reviewers had the same problem. Save yourself the money and frustration and try another product. I should have read the reviews more carefully. I've had this a month now and am resolved to buy something else. I liked the look of this design. It looks like it should work, but alas, not true!This thing slips off the cans 9 times out of 10 uses. Something a simple as a can opener should work every time it's used, without any adjustments. It will open a can, but only after resetting it 2 to 5 times on a single can! Ridiculous! I will end up throwing it in the trash, a waste. I would donate it to a charity, but I would feel bad about someone else ending up with this dumb, poorly made tool!
