Opens the can weird, but functional
Color: Black/Battery
Ehhh it’s easy to use and gets it open, my only issue is that it doesn’t open a can like a regular can opener where it is cut on top of the can and you can push it in the can to drain if needed. Rather it cuts the outside of the can as it spins around, so it doesn’t fit inside the can. Not very handy when you’re opening a can of tuna and want to drain the tuna juice, so I had to keep my manual one, that I was trying to get rid of by buying this electric one 🙃

Works Great!
Color: Black/Battery
I've only used it a few times since it arrived and it works great. Much better than the hand cranking can opener I've been using. It's a little loud, but that's not enough of a deterrent for me to stop using it. The noise is a temporary annoyance that I'll gladly put up with to have a can opener that actually completely opens a can.

Super convenient and easy to use!
Color: Black/Battery
This electric can opener is a game-changer in the kitchen. It operates smoothly with just the press of a button and leaves safe, smooth edges on the cans. Very compact and handy.

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.
