Broke after only like 5 uses...not worth the money. Doesn't stay sharp nor does it auto-clamp onto cans after such uses. Thought it worked only to find out it didn't cut the can and left little metal shavings from just kinda "scratching" the can and I ended up getting a splinter. Thought it was low on battery and fully charged only for it to keep not cutting the can. Trashed it just gonna buy a regular stand up from walmart or something.
