Question: Does it have an auto shut off when the can is opened?
Document: I had a can opener that drove me nuts. It was a chore just to get one can opened.I saw these can openers on Amazon and thought they couldn't be any worse than what I already had so I ordered a set of them. It was one of the best things I did. These can openers are so easy to use.
I had one of these that lasted for years. I missed it when it finally stopped working. Saves on the hands and saves time. Easy to use, only uses 2 batteries. Couldn't find in stores. This price was right. Now I have a spare or one to give away! Best way to get a can opened. No sharp edges.
I purchased these can openers as a replacement for one that my mother was using. She is 89 with arthritis which made it difficult for her to use a can opener. I purchased a counter top electric can opener for her originally but she still had trouble operating the electric can opener. I liked this can opener so much that I purchased one for myself. Silly maybe, but I like that I can do my other cooking tasks while cans are being opened.
works great! and was very reasonably priced. wish I could have picked the colors, love the red, but not partial to the grey color
these were the worst can openers i have ever had poor quality and they came i n one colour  grey  and  grey.they went to the dump
just tried it once. you need to actually put it on the can before turning on as the magnet must connect.
i purchased this opener for my husband. He only has one hand and i needed to find something easy for him to use. I could not use the darn thing with two hands. after the first use the opener was stuck to the lid. i tried to use the manual release but it did nothing. the lid is still attached to the opener which is now in the bottom of the trash can!
i have had a hand crank can opener for years,and finally got sick and tired of wearing my wrist out every time i had to open a can. so, i decided on an electronic one, and this little gadget works wonderfully! i've had to once in a while stop it on smaller cans, but no big deal; other than that, i highly recommend this. i got the 2-pack so i would have one, and i'll give one as a gift for Christmas or a birthday.
Worst can opener ever. don't waste your money. It doesn't work and after you get tired of wrestling with it and set your mind to just using the manual can opener which would have taken all of 30 seconds....this piece of crap is lodged in the can and will not let go.
Works great. Very impresses. I bought couple of these for my friends also. The cut is smooth as described.Thanks
Answer: Yes, it does turn off automatically.
