This can opener cut off the whole top of the tuna cans and left an insanely sharp, wobbly, very thin edge of the top of the can that nearly cut me because there was no heavy metal lip left behind to hold the structure of the top of the can! This is a very bad feature that is going to really hurt someone! I do NOT recommend this for anyone! Needs a product recall!

Lackluster

Color: Black, Color: Black

It does what it’s supposed to but only for a couple of cans before it dies. I’ve learned that I have to charge it before I put it away or it’s dead when I need it next and that’s after 2-3 cans. It’s small and fits in my drawer nice, does what it’s supposed to, just a little disappointed in how long it lasts

Don't mind the noise

Color: Blue

Works great, does exactly what it is supposed to do. Just very loud.
