Bests & Worsts Reviews from Amazon

This is the first OXO product I've been dissatisfied with. Unfortunrtely, this jar opener is useless. I purchased it to replace an old OXO jar opener that I've had for years, but has somehow disappeared . The old one had "jaw teeth" on both sides, but this new one has the teeth only on 1 side. The other "jaw" is polished metal, so it has zero grip surface. Even moderately tight lids will not open with this device. It slips long before the lid moves, no matter how hard I squeeze it. I asked my neighbor, a younger very athletic man, to try it, and the same thing happened. He squeezed so hard he thought it may break, but the device slips, and the lid does not turn. He was easily able to open the jars with only his hands. We experimented a little, using less squeeze-pressure, then more pressure, but nothing worked. Jars of olives from the fridge would not open. Jars of honey would not open. Mason jars would not open. This device is useless, except maybe as a paperweight.
