Product review (3 stars): I almost tossed the thing in the trash as a wasted purchase, but some of the Q & A ...
Works okay, but the instructions are inscrutable, written in that broken English you get when Chinese (?) is fed through google translator (or whatever).  I almost tossed the thing in the trash as a wasted purchase, but some of the Q & A here helped to make sense of things (thanks, folks).

Oh well, what do you expect for 4 bucks.
