I stopped using mine the day I got it because it emitted a annoying loud whiny noise the second I plugged it in. I immediately thought "cheap Chinese manufacturing" and started using my white iPhone charger instead. Glad I did.

What makes this more serious is that the WakeMate seems to be really power hungry and needs almost constant charging - I've noticed that it usually can't go 2 straight nights without a recharge. Since that's the case, I imagine most people just plug it into the defective charger each morning, so it's plugged in for about 16 hours per day. But maybe my battery is also defective ...

Not sure how these two are different technically (both probably have similar accelerometers), but I also have a FitBit that I wear all day long - yet I only need to charge that guy maybe once a week.

Hoping the WakeMate guys get through this, though ...
