Review (3/5): The battery is good for about 30 minutes
We have been using this product for six months - it works! We feel the rechargeable unit is over priced. The battery is good for about 30 minutes. The electronics are poor as you do not know the battery status or when the unit is recharged. Recharging takes many hours and you don't know when it is fully charged.
We would not purchase this product again but would consider the plug in unit.
The pads are holding up much better than we expected lasting very well.
It does an excellent job removing the dry skin and calluses. We recommend the technology but not this model.
