Pleasantly surprised at how well this works. My feet tend to be very dry and catch on everything - they feel a lot like the grabby side of Velcro. Even a recent pedicure was unable to keep them smooth for more than a few days.
Using the lightest grinding head, I was able to remove a large amount of the dry skin. I was left with smooth, soft feet that don't catch on anything! It is quite quick, so I can see using this on a weekly or twice a week basis to keep my feet nice.
There is a display that shows just how charged the battery is, so there is never a doubt about how much more you can do before needing to stop and charge. The grinding heads are easily removed and snapped into place again for cleaning or changing grinding strength.
This was a really nice price point and I think it works like I would expect a much more expensive grinder to work.
