WOW. I've tried many jar openers over the years and had no idea one could be as effective and efficient as this one. I have several jars of pasta sauce that I could not open trying a number of mechanisms, which I was about to take back to the store. I got this item delivered just in time - this one got the lid off in a matter of seconds, and I'm now eating pasta tonight!It works exactly as described -- adjusts to fit the size of your jar lid and grips securely onto the lid until you get the lid off. Far better than the Oxo jar opener, which I also have and which just managed to dig into and scratch the pasta sauce lid without opening it (and I'm a big Oxo fan -- have a lot of their products).I highly recommend this product -- this is one of those gadgets that completely wowed me.
