So simple to use, I'm amazed
Color: Black
Wonderfully helpful. Description is accurate, shipping was quick. I saw a few poor comments, but I have none so far! The can opener has opened cans of several sizes, from tomato paste to large cans of tomatoes; soup cans to strangely shaped. It's opened 30 or so already without loss of power. It's a little noisy, but about equal to that of a stand up opener. It fits in my drawer, which is less deep than most kitchen drawers. Most of all, it's beyond easy to use for arthritic hands. The ONLY CHALLENGE I have is that it sometimes fails to stop when it should. MANUFACTURER: if you read this and have advice, please share. At this point, I'd say this is a great value for the money.

Pleased be careful
Color: Black
Please be very careful when using this. After using it 2 times it opened cans just fine. Then it stop opening cans and will make hair like strains of metals and one would think its hair and pull on it thus Cutting your fingers open. That’s what happened to me. Please be careful.

Quit working after 30 days
Color: Black
This can opener worked fine for the first couple of weeks. It stopped working several days ago and even though I had recharged it, it would not turn on. I thought I would give it another try before I threw it away since I was past the refund period so I could not return it. I made 100% sure that it was plugged in securely and it did charge and worked today. Make sure that it is plugged in securely when charging. Hopefully it will continue to work and if not I will update my review.
