Great opener
Color: Blue
Had a battery operated can opener before and was always changing the batteries. Love the safety cut and this works great now that I can just charge it with my phone charger. Fits in my drawer so no counter space used

Leaves an EXTREMELY SHARP edge - cuts off entire lid from sides of can!
Color: Blue, Color: Blue
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
