Injured finger from use
Color: Black/Battery
Just used the product for the first time today. Beware, it does work but it cut my daughter’s finger open really bad because it made the edge of the can stringy and she cut her finger on it. Be careful.

Super practical and easy to use 👍
I bought this electric can opener from Kitchenmuh and I absolutely love it. It's super practical; with just the push of a button, it does all the work effortlessly. I really like that it's hands-free, which makes it ideal for everyday use, especially when you're busy in the kitchen. It opens cans smoothly and safely, without leaving sharp edges, which is a huge plus. Plus, it's compact and doesn't take up much space. So far, it's worked perfectly and feels like good quality. I definitely recommend it; it's an excellent helper in the kitchen! 👌✨

Great Safe Can Opener
Color: Black+Grey
The 1️⃣ touch can opener is great⭐️⭐️⭐️⭐️⭐️. It is easy to use & eliminates possible cuts to my hand on those cans that have a pop up lid. I am almost 70 so sometimes using a manual can opener is difficult.
Thank you for selling a quality product at a really fair price ⭐️🌈⭐️🌈⭐️Donna Pearson in New Orleans

Great, leaves top of can Very sharp!
Color: Grey Red
Tried it out the second I got it today. Works great.
Just know that it leaves the top of the can VERY sharp!!! So if you are scooping things out, use a very long handle like a spatula.
Will add another star if it lasts more then 6 months
