This is powerful
Almost too powerful. I was used to the battery powered one. This one requires an adjustment in technique. It works well and does what it’s supposed to do;  remove calloused skin. As long as it works I’ll be happy. I’ve only used it twice so I can not speak to its durability. My battery powered unit died after a few years of weekly use. We’ll see if this one fares better. I am hopeful.
