You should probably update the price column. It still says $49.99, although the price increased to $59.99.

Nice thanks. Might I suggest you make the compare chart more accessible. Even now knowing it exists I took another pass through the site to see how I overlooked it and I still can't figure out how to navigate to it.

edit: Finally found it as the LAST item on the FAQ. I still think you should make it more accesible! Cool

is your product the only one that will determine optimal wake-up time? will fitbit do it?

can you link us to the paper you use to determine optimal wakeup time? or do you just use it on analytics based on user-generated reports.
