We purchased an Inspire when my wife's Fitbit One died after about 6 years. We are only interested in step and sleep tracking so the Inspire seemed like the best bet. It tracked my wife's sleep for the first 2 nights and then stopped. We called Support 3 times about this issue. The first time they made some minor settings changes and rebooted the Inspire. The second time, they set the settings back to where they were. The third time, they didn't know what to do. I suggested that since the product was defective, they should send me a new one. The agent told me that the problem wasn't in the product, it was in their system and the technical team was working on it. I asked to speak to a supervisor and she told me that the Inspire didn't monitor sleep. I informed her of two things: first, the product description clearly states that it does sleep tracking and, second, it had tracked my wife's sleep for 2 nights. She reluctantly agreed to send us a prepaid return label for a refund.
I have some issues with the way that Firbit says that they automatically track sleep. According to their literature, you have to go to bed and be motionless for an hour for the Inspire to determine that you are asleep. This is preposterous, of course. Who remains completely motionless for an hour? For example, suppose my wife gets in bed and drifts off to sleep after 10 minutes. 55 minutes later, she turns over. The Inspire, according to Fitbit, would not assume that she was or had been asleep. The hour of being motionless would be reset. This sequence of 55 minutes motionless then a movement could go on all night, in which case, the Inspire would never go into sleep tracking mode. It seems to me that the basic algorithm is wrong. I would much prefer manually activating the sleep tracker as the Fitbit One did. We are very unhappy with Fitbit, not just because their product doesn't work as advertised, but also because their customer service, which was quite good 6 years ago, is not very good today.
