Query: One touch? try don't work and get stuck

I don't know if I got a bad one or what but when I tried this gadget it didn't work and never has. I've had it for months now and it still doesn't do what it promises. Mine rode about a inch around the can and then stopped and when it stops it's locked onto the can and won't come off. I spent forty minutes trying to get it off of the can. When I received it I was sick and my young son took it out of it's shipping package and threw away the paper work so I was unable to send it back so now I'm stuck with this useless junk. And yes I did put fresh batteries in it.
