Review title is Power to the Max [SEP] This electric callus remover has some serious power. It's a sandpaper power tool disguised as a pedicure accessory. It works really fast, almost so that I use a tapping motion when using it so that it doesn't tear too deep into my skin. The lowest setting is incredibly strong. Anything above that is like used to remove grout or something. It's a little loud though but it will take you up to 3 minutes to do both your feet. The cord is a reasonable length (9 feet) and it comes with extra head replacements (which you can also buy more if needed for less than $10 a pack). This is some professional industrial grade callus remover. It has a nice design and easy to clean. Overall, highly recommended.
