Title: Aughhhh, competely useless!
Review: I have always wanted one of these and finally wasted my money and bought one. More pressure is needed to hold this device on the lid of a jar than it would take just to open the jar in the first place. If you are buying this because of small hands or weak grip, don't bother. My husband can make it work, but by the time he is in the kitchen he can just open the jar for me. The teeth to hold the lid are shallow and slip off the jar if you don't apply enough downward pressure. I have never been so disappointed in a kitchen gadget!
