Review on Ultimate Electric Callus Remover: Rechargeable Foot File Pedicure Tool, Vacuum Adsorption Foot Grinder with 2 Speeds & 3 Grinding Heads - Powerful Exfoliation for Dead Skin, Portable and Professional by Kim Tyger

Works decent for the most part. It does a pretty good job of filing down calluses on the feet with the rotating disc and collecting the dust on the foam filter disc inside. It has 2 speed settings and comes with 3 color coded burrs to suit your needs. A micro USB charging cable, spare filter disc and metal nail clipper are also included. The only thing I don't like about this tool is that its motor is not very powerful. It slows down significantly if you press the rotating disc hard against the corn. The vacuum cleaner mostly works, but still a lot of dust ends up on the floor. You will also have to clean the filter inside from time to time since its function is to collect all the dust on itself. Last but not least, it looks a bit cheap. The back cover opens easily, exposing cheap plastic on the inside. Overall, this tool is just decent. It's easy to hold and navigate in the palm of your hand. It's not the best and certainly not the worst rotary callus remover I've ever used. In any case, it does its job.
