Bests & Worsts Reviews from Amazon

This is the second one I'm returning! It stops upon contact with nails or skin and the battery will not hold a charge for even a few minutes. The first one did the same thing, so I purchased another from a different seller and it does the same thing. I hate returning things but the last few things I've purchased from Amazon have had issues and should be discontinued. It's a waste of my time to shop for things only to have them not work then have to spend more time and gas to return them.
