An elderly woman came into our office one day and was talking about ordering one of these gadgets for a bridal shower. She said she has used one of these for years and wouldn't want to be without it. She has arthritis in her hands and can easily open any jar with this. She said she buys one of these for every new bride as she thinks it's very useful for anyone. I ordered me one that day and have been using it for almost 3 years and I love mine! I too think every kitchen needs one of these. They are super easy to use. Just slide any size jar lid in the opening and give a twist. You can keep it in a drawer or screw it under a kitchen cabinet. This is a Pampered Chef product that sells for $12. 25.
