Subpar quality, defective charger/battery
Just received it yesterday, and was really looking forward to using it on my bad shoulder.  But not sure if I got a lemon or a returned item (the defect is almost the same as another reviewer), the battery won't charge.<br />- The screen was dislodged (it was glued on); I just push it back in.<br />- Plugged it in to charge and the ring at the bottom flash yellow slowly.  I left it charging for a good five hours.  And it seemed to have shut off automatically.  Thinking it was fully charged, I turned it on and it showed only 81% battery left.  Without touching anything, it started dropping to 78%.<br />- I tried it anyways, and it seemed to work fine; but then the intensity level started increasing by itself a couple of times without ever touching the screen.<br />- Plugged it back and see if it will charge, but nothing.  The ring would not turn on this time.  Left it plugged in and see if will charge, but still nothing.  And the battery drop without touching anything again.<br /><br />So, not sure it's the batter or charger, or something else.  Poor quality and unreliable screen.  When it's working, it seems solid and powerful and not too loud.  I have contacted seller and see what the respond is.  Otherwise, I'll just return it.
