I finally tried using the Fitbit I got a while back for some work fitness promotion. Cost me $125 bucks at the time. Sat on a shelf for a while - way past any return policy or warranty afaik. (And it's not like I still have the receipt or anything.)
I had it working for about ten minutes, and it was kinda neat, but it tried to update its firmware and got hosed - now it's stuck in a reboot loop. It'll get as far as showing the time, but then crashes and reboots, and shows the splash screen (v122) again and again.
I was interested enough that I bought a used one (same model) on eBay for $45. It came today, even though it wasn't supposed to be here until tomorrow (the seller is just the next state over, so that's not uncommon.)
It works fine, except it's got the (older? Presumably older.) white-on-black screen on it, instead of the brighter blue LED one that my newer one has. (had?) Also, it's black instead of blue, so it's not as chic. It's got v64 firmware installed, and it will STAY THAT WAY.
So I spent $170 on a fitbit, like a motherfucking boss. Would rather have spent it on a trash can.
