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 ...
The fitbit tech is pretty primitive -- it looks like it only has a pedometer inside the device. It's probably why it isn't very accurate at tracking sleep. I've been using my fitbit for a few weeks, but it doesn't seem very accurate at all in general.
According to https://secure.wikimedia.org/wikipedia/en/wiki/Fitbit uses a 3D accelerometer, so it seems to be more complex than just a pedometer. I've found it to be quite accurate for daytime activity, especially tracking when I'm being really active. But I'm just now starting to use it to measure sleep (and to compare the results to the WakeMate while I'm at it), so can't speak much to its effectiveness yet.
I think your battery might be defective. My WakeMate loses about 19-20% battery life each night. I was using the original black charger... looks like I'll be using the real brick from Apple now.
