I got a random vibration a few days ago, but everything was still looking good. After a sync I still had 70% battery. The next day it happened again and this time I couldn't get it to light up at all. Tried syncing it and it failed. Charged it and started working a few hours later. Went for a run and then it stopped syncing. Tried to put it in sleep mode when I went to bed and it wouldn't do anything when the button was tapped. Charging doesn't seem to do anything to it either.
Our support team can definitely help you troubleshoot these issues! If we can't resolve the issue by resetting the band, we can absolutely look into warranty options and help with a replacement.
I've opened a support ticket for you, so that we can resolve this as quickly as possible.
