Such a convenient little tool
Color: Red/Battery
Once I figured out how to use it, I wondered what took me so long to purchase it. Very easy to get the hang of using. Not too fast, not too heavy, not too noisy, just perfect can opener without all the hardworking and spilling contents all over the place.

Don’t buy it
Color: Red/Battery
Stoped working after 6 months. I wish I had purchased the same one I had, Kitchen Mama, but the price was better for Circle Joy. Silly me I won’t be fooled again. I have arthritis and can’t use manual openers. This is going in the trash today. Btw- I only use it 1 or 2 times a week.

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.
