So...my Fitbit died over the weekend. After owning it for only two months.
Needless to say, I'm not impressed.
I won't be buying a new one. From the looks of it, it's not really worth it to bug customer service about getting a replacement, either. They seem to be good about that, but the short life on it seems to be endemic to the brand. I'd rather not go through a cycle of having to get a new one every couple months.
Is it worth it to look at other monitors? I don't know. Do you have one you like?
