I decided to give this a try despite the bad reviews.  DON'T DO IT FOR THE FOLLOWING REASONS!!

1) It is extremely cheap feeling.  Very light and it practically slides around my dresser when touched.
2) The LED light is an annoying blue ring around bezel of the opening.  This thing lights up my room at night.  Not cool.
3) It worked fairly quietly for the first 2 days, then the entire unit starting vibrating uncontrollably when it was in use.  I found that I could stop the vibration by adjusting the placement of the watch slightly, but that isn't something I want to do each time I swap watches.
4) This is a minor annoyance.  The unit's minimum TPD is 1440 with a maximum of 2152!!  That is way more than necessary.  Most watches need 650-800 TPD.  Waste of energy in my opinion.

Gave it two stars because it does work and it has options for CW and CCW at various intervals.
