Coocotech USB 3.0 to HDMI VGA Adapter with Audio Powered by Ezcast, Digital AV Converter for iOS/Android Mobile Phone Tablet

Update: fire tablet and iPad didn’t workWell I received the second one and today I understood I need to turn on the adapter with usb/micro cable first, then connect iPhone to adapter, then connect adapter to hdmi cable then hdmi cable to tv and then FINALLY tv showed up the instructions and THEN it connects screen mirroring but didn’t changed tv screen UNTIL I open the EZCast app and watch everything THROUGH EZCast app otherwise doesn’t work. Takes time to load videos shows buffering and I just ordered an adapter from Apple to see if it’s gonna take same time to load videos but so far I.ll keep it just need to load everything before plays :) thanks for help
