Product review (1 stars): ghost controlling it
After 18 months it starts turning on and off for no reason.  Wtf!  I am going to battle these hooligans to fix this.  Do not buy this.  Update:  I fixed that issue by removing some chip from the circuit board.  It worked OK for a few more months until....it didn't.  Now it just blinks on and off ALL THE TIME.  What a piece.  My fault for not reseaching this better.
