    Returning
  

*by E***H on Reviewed in the United States on March 20, 2020*

When I first took it out of the box, I put it on the charger. It charged for a little bit. While it was charging I tried to do some set up with the app. The device never fully charged. I kept it plugged in for 2-3 hours. I was never able to get the device to turn back on. I tried different chargers and different cords. No luck. I never got to use the device. I'm going to return the device as soon as possible.
