Question: Why won't it work?
Document: this is great! I've only used it once, but if it continues to work like it did the first time, it's a winner!
The handy can opener was just what I was looking for. It was a replacement for a similar opener that had given up the ghost. Does work well.
Replacing the batteries didn't work. This is a piece of junk. Don't waste your money. Threw it away after 2 weeks.
I had it for two weeks and the can opener broke! Even tried to replace batteries and still did not work!
Not a good product. Quit working within 2 weeks. We replaced the batteries, it still don't work at all. Useless! !
Never could get it to work at all..my mother has one I bought her at Big Lots and it works fine..
After only 6 weeks it stopped working, changed the batteries and it still won't work. I just ordered a different brand!
After one week it stopped working. Changed the batteries and it still doesn't work. it's useless. A waste of money.
this product only worked the 1st time i used it . the times after that it did not work well at all . it also left the inside of the can with a very sharp edge.
This item is china junk and does not work.I have tried two and first worked for short time. A waste.
Answer: I had two of these and neither worked more than twice.  Bad product.
