Fantastic Product!
I am so glad I finally took the plunge and purchased this!  I own the battery powered version, but was too cheap to upgrade.  This version beats it hands down!  I used to think I needed to replace my roller but it was the weakening batteries causing less than optimal results.  Now optimal speed at all times!  NO more feeding it batteries!  Now my feet are in shape for the summer!  Sigh!  Wish it was this easy to get the rest of me in shape for the summer!
