DO NOT BUY Fitbit IONIC, there has been a lot of issues.
I have tried most of their products from surge flex 1 and 2, charge HR, blaze.
this is the worst one.
Had called customer support 3x for the same issues and I can't even get a replacement.
They want to fix the issues but apparently they haven't.
the flyer headphone is one bad product too.
I am not of those who just complains. I have wasted so much time to fix this issue.
