I love this Feet Grinder, it's like you've been to the nail and foot salon. You plug it in the usb port and you can use it then, or you can charge it and it doesn't take long at all.
This wonderful little wheel will remove the rough places on your feet like a miracle. It is also fabulous for filing nails and any number of grooming things where you want to gently turn your skin satiny smooth and soft. Have used these for a lot of years and hope they never stop making them or - gasp - try to "new and improve" them. They are simply perfect exactly the way they are.
Very easy to use and great results after first use. I've used other products in the past and this one removes dead skin better and the softness last!!
