Product Description Black & Decker JW200B Lids Off Jar Opener, Black Amazon.com With the Lids Off jar opener, Black & Decker has simplified the opening of jars to a no-strain, one-hand operation. Electrically powered, the Lids Off cradles a jar on its lower turntable then grips its lid when you lower the upper housing. Push the large power button, and—voila!—the lid is twisted free. Designed for use on metal or plastic lids, the opener makes a handy tool for anyone and can be especially helpful for those with weak hands or arthritis. The unit accommodates a wide range of jars, from baby food to spaghetti sauce, anything up to 4-1/2 inches in diameter and 8 inches high. It is not intended, however, for the very narrow necks of beer bottles or tall jars of juice. Measuring 8-1/2 by 7-3/4 by 10 inches, the Lids Off is collapsible for space-efficiency and comes with built-in power cord storage. --Emily Bedard
