Item review update! Disregard my first review since then I realized that I didn't have the usb cable pushed in far enough for a connection which stopped the item from charging and that's why it stopped working. Item works as described, clean cut, easy to use and really worth the cost. I definitely recommend.

Very Easy to Use, no stress on your hands

Color: Black

I am 76 and my hands don’t grip the way they used to. Too hard using a manual can opener. This one definitely fits the bill, plus I like the rechargeable feature!

Very poor quality. Not supported by manufacturer.

I bought this because of my arthritis. I could not use a manual can opener anymore. Worthless product. It lasted 3 months, only cut soft aluminum cans. No response when I emailed the company. Do not buy this product.
