    I bought the Fitbit Flex to sleep in. My One doesn't have a wrist band anymore and I want to be able to monitor my sleep. As a second Fitbit is is good. I like having a second one especially if my One battery needs to be charged.

    I think I just got a bad flex. I could not get it to completely sync and my previous days information would get lost. Submitted ticket with Fitbit and they think it is due to my account and are looking to try and fix it. In the meantime I returned the product and will try again when and if account gets fixed.

    I wish the app would provide tips based on how my day was. Sum up why I did not do right and why I did not lose what I should.

    It caused all other apps on my phone to stop working. I also had to keep deleting and re adding the app because the Fitbit was not syncing it just continued to say searching. Way over priced and I made a huge mistake buying this item.
