Excellent can opener.
Color: Red/Battery
Love it! Works like a charm. I have arthritis which made opening cans with the type I’d used for years very hard. I didn’t want one on the counter, this fits perfectly in a drawer. I know a couple our friends have ordered one.

Worth the Money
Color: Red/Battery
I bought this thinking, "Will it really work the way it shows?". The answer is yes. Put it on the can, press the button, and then it does its thing hands off. It does leave a smooth edge too. Not too speedy, but better than having to fight with your manual to get it to catch the edge.

The best can opener ever
Color: Blue/Battery
I love it. It’s so easy to use just press the button. It’s spins around the can. The lid comes off without any sharp edges. It’s a little loud but works perfect. I’m basically any type of can. Great on those big cans of yam.
