I stopped using my wakemate after maybe 3 weeks mostly out of frustration. I was never able to score higher than 65 despite sleeping for long hours, short hours, etc. (is my sleeping really that bad every day?). The other thing that frustrated me is all the data is useless unless you tag it and create your own trends to follow, i.e. I sleep better when I [exercise]. I sleep worse when I [ate before bed].

The thing that really got me though is that every time you have to type in the same tags over again, you can't pick from previous tags, which got old fast.

Oh, they also never sent me back a charger after they told us to throw it out (first batches of Wakemates had faulty chargers) :(
