Bests & Worsts Reviews from Amazon

Very disappointed that the device's HR stopped working after a few months and with Fitbit's response to the problem. I've had the device for about three months, and it worked well. The HR tracker is not perfect and can fluctuate significantly (which is to be expected), but in the past few days it's gone haywire. I called and spoke to numerous Fitbit customer service folks, and they offered a number of reasons why the HR tracker wasn't working. Some--like saying that my HR was 30-40 BPM higher because I wasn't as active for a day--were ridiculous, while others were more credible. Long story short, the problem with the watch is most likely mechanical. It was working fine, but then stopped suddenly, with no intervening software changes (that I'm aware of, at least) or changes to how I wear or use it. However, Fitbit outright refused to honor the warranty and service the watch, and the last rep became somewhat hostile when I continued to press for an explanation why. Don't spend so much money on a device that'll break down so soon, without (apparently) even a limited warranty to back it up.
