Day 11. I got a response.
This e-mail is to confirm that we’ve initiated the warranty exchange for your UP band. Please expect another e-mail from FedEx with a prepaid return shipping label within the next 24 hours.
Please return both your UP and the charging cable you use with the band. We will be shipping you a new, fully packaged unit, so you’ll receive a replacement charger as well.
Great! I am going to get a new band. Here’s for hoping it works!
Now, I am just waiting for a label from Fedex. At noon I received the label. Quick.
Once shipped, two days for processing and overnight delivery of a new band back to me.
