Well all I can tell you is buying this machine beware that the lowest speed is super high I don't know how anybody could use this machine to remove hey callus and not worry about causing a skin burn even with moving the device around it's still got way too hot. there has to be some speed to lessen the lure speed as it feels almost like the high-speed I actually turned on a power drill that has adjustable speeds and found that it had better setting than this device. So I'm buying this just be aware that the lowest speed is the equivalency to about a medium speed on a power tools.
