Easy to operate.
Color: Black/Battery
Very easy to operate. I was a little confused on how it operated but all I had to do is sit it on top of the can and it operates by itself. When it is done, the lid can be removed or set on top of the can. It doesn't leave any sharp edges. I was using a hand held one but because I have arthritis in my wrist, it is worth the price easy enough for seniors or disabled

Only worked for 1 month.
Color: Black/Battery
This product was delivered on April 20th and worked great. It made a nice clean cut in the metal with no sharp edges and the top of the can lifted up nicely. Yesterday, May 24th, it stopped cutting and unfortunately, the return window closed on May 20th.

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 🙃
