I got this as part of a review, so have only only used it once, and it has been such a great quality!
NOTE: The Wireless Dongle it came with, is meant to allow you to screencast from your Android or iPhone, but its a very cheap one made in China and doesn't work properly, so I am not selling with this (you can buy wireless HDMI miracast dongles for about £8 if you want one, but I dont recommend it). So I recommend you to buy a Google Chromecast or connect maybe an Apple TV if you have an iPhone, but outside of this, I am selling this without the ability to screen mirror, hence the big discount!
