If you have an inconsistent sleep schedule, dont b
Wore for two nights and still no sleep data in the garmin connect app. Checked the garmin support site and apparently if you happen to go to sleep outside of the set sleep schedule settings in the app your index sleep monitor doesn't record sleep data. Tf?? So you mean this device is pretty much USELESS if youre a pilot, nurse, physician, locomotive engineer, or anyone without a set sleep schedule?? People who need to monitor their sleep the most! I will try setting the sleep schedule basically to encompass the entire 24 hours. If that doesn't work I'll return it.
Device bricked after two nights, support useless
After two nights of recording my sleep, the device would no longer sync. After removing the device from garmin connect, I could not re-add the device to garmin connect as it would fail silently complaining about "bad pin / passcode". Garmin forums mention one other person having this same problem, with no fix besides replacing the device. Garmin support was pathetic in just copying and pasting pairing steps from the manual, which I had mentioned I had followed exactly, and asking me to record a video when I provided detailed step by step descriptions of how it was failing. This product is half-baked, and the fact they're asking me to record a video shows that they are treating early users like beta-testers instead of paying customers.
