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. ### ⭐⭐⭐⭐ works with windows phone but not well *by R***. on Reviewed in the United States on April 14, 2019* Had a hard time updating the program on Windows Phone..
