My wife and I just got Inspire HR.
Mine will track my sleep nearly to the minute, while my wifes will say she is sleeping while watching tv.
She was watching tv the other night, it recorded it as sleep, even while she got up, did some cleaning in the kitchen, had a bath and then went to bed.
Last night, it recorded that she was sleeping while we were watching tv.
On top of that, my battery life is twice as long as hers.
