Try another product
The first thought was very low power, but, I decided to try it.  I used the product about once per week and it did make my feet smooth.  However, had to change batteries often.  This past weekend, it stopped working.  The motor simply stopped with brand new batteries. It is not worth the time or the money spent.  In the future, I would probably purchase a product made in the US and one that is rechargeable.
