Love it takes up less space and easy to use
Color: Grey Red
The can opener works awesome easy to use and the magnet helps hold the lid after use. Easy to clean and easy to stack to the can. Batter life seems great and the product seems durable no issues. Highly recommend.

So far
Color: Black+Grey
I did have a electric can opener before and that brand didn't really work well at all. With this one I have only opened 3 cans with it so far and it worked perfectly. I am very happy with the product and it is really easy to work with. I didn't know if it was going to work on a bigger can and when I put it on it did the job just like it is supposed too.

Frustrating Opener
Color: Black+Grey
I love and hate these at the same time! I have had several and this one will not stop once it has started! Even though there is a button that says start/stop whenever you push it, it just starts it all over again and I can’t get the lid out. Very frustrating.

Effortless opening and no sharp edges.
We recently went camping and realized we really needed a reliable opener, and this one was a lifesaver. It’s incredibly easy to use, you just set it on the can, press the button, and it does all the work for you. I love that it leaves a smooth edge and feels sturdy, plus the black finish looks really nice. This has quickly become one of my favorite gadgets for making meal prep much faster, whether at home or on a trip.

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.
