I had hoped to use this product at the grocery store and was sorely disappointed with how useless it was. For small, light items it was fine, but for larger items (i.e. jar of spaghetti sauce, pack of meat,small bottle of salad dressing) it quickly lost gripping power for items over 1 1/2 lbs. It could not effectively grab a knob to turn on the stove, or grab a cabinet handle. For small, light things,it performed beautifully.
