This Review Title is Very disappointed! and the content is: Shipping was fast...the product stunk.<br />The battery cover wouldn't lock into place, so I had to use duck tape to hold the batteries in.<br />I tried the roller it shipped with, & after 5 minutes of use, my skin hurt.  But my light calluses weren't even smoothed.  Waste of time & money!.There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
