Better than manual callus remover
It works better than manual file or stone. It works faster and you have more control as you don't have to scrub and position at the same time.<br />The grinding rollers come in 3 different coarseness but I find that only the fine roller is needed as you really should not remove too much callus at once as you can damage the skin.<br /><br />It comes with USB-A to micro-USB cord. It does not come with a charger.<br /><br />Pros: It is effective. Performance is same as similar looking other brands. Sturdily built.<br /><br />Cons (especially compared to my other unit):<br />  1. It turns on at full speed first. The button has to be pressed to go half-speed. It should start at half-speed. Really don't need full speed anyway.<br />  2. The switch is too easy to turn on accidentally. Often it came on while changing the roller -- ouch! Not good for packing with travel stuff.<br />  3. Kind of big. I have another one which is smaller and easier to handle.<br /><br />Note:<br />One of the roller was defective and would only spin idly because the spindle was too short to engage the motor. See in the photo.<br /><br />Overall, it works. There are others with better usability for a bit more, though.
