Query: Don't waste your money!

I bought this thinking it would be a helpful can opener and easy to use. After the first can it died 1/2 way through with good batteries. I then tried a lighter weight can with another set of "new" batteries. After what seemed a lifetime, the can was open. I threw this piece of junk in the trash! Would rather use a pocket knife. I wouldn't buy it!
