Review on 📺 10.6 Inch 4K 1080P Android 9.0 Universal Headrest Monitor Video Player for Car TV - Touch Screen, WiFi/Bluetooth/USB/SD/HDMI, Headset Support, FM/Airplay, NO DVD (2GB RAM, 16GB ROM) by Michael Wiley

Product has good picture quality 8 out of 10 Check your screens as one of my devices had a few dead pixels of which about 4 remain white. Android OS is not good 6 out of 10 System crashes and the screen goes black, you can fix it by restarting the monitor. HDMI only works for mirroring your phone and some apps. Hulu, Netflix, and Roku don't work, but YouTube does. You can download apps on your device and use it like a tablet, they work but if you don't have good wifi they freeze all day. The phone's hotspot works with the device but lags behind. The sound quality is poor, so do not use the built-in speakers. The kit includes all the cables you need to install the devices in your car and is very easy to install. You have 2 options for installation. The price of the device is high in my opinion only because the Android OS is bad and crashes from time to time.
