JOKE WASTE OF MONEY
This has absolutely no more power than the cheapest battery operated one from wish. I have a five dollar battery operated one i got from five below has way more power than this thing. Don't waste your money I should have listened to those reviews instead of the positive ones because those people are obviously lying if they think this has power, It stops with the slightest pressure. Tried to upload a video but wouldn't go.  It is lightweight and will eventually grind some callus off i guess if you have a week or so to wait. It's going right back for a refund.
