I have wanted a lumie bodyclock for years after struggling with waking up happily in the darker months. Nearly all the reviews are excellent, and yes the dimmable light is pretty good (I find the sunset better than the sunrise), but the main issue for me is that it does not keep time. Within a few hours of setting up my first bodyclock it had lost 2 minutes. Cue several attempts at moving it on to the correct time. But it continually loses 2-3 minutes each day. Sent this one back, but a week into using my replacement bodyclock it is doing exactly the same. Has anybody else found this? I Really want to have a bodyclock but am not confident that this would not be a constant problem.
