Can opener
This product does not work well! It actually doesn't work at all!! Will not cut thru can lids at all. Very disappointing to say the least. I purchased to make things easier only to be left not being able to open dinner 😕. Would not recommend to anyone!!!

Can opener
It doesn't shut off by itself when done and doesn't shut off when I push the button, so after a while it will shut off but when it wants too after you take it off the can ,like 30 seconds. But I do like the way it cuts, a clean cut and lid removal nice.

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!
