I use it heavily for five months now. Great streaming maschine for downloading movies and series and simply incredible in live tv. You get 720p and 1080i at ease. If you want 4k ... get real and buy a better tv. If you like football and sports this is the box for you. You have more ram memory than you will ever need and if you have an adequate internet speed then you know you have done the best you could to stream anything streamable! Only a weak source (or a locked source...) can stop you from watching whatever you want. Very good for playing games also (not my thing). I have just put a 64 gb micro usd card in order to make a large movie library (over 90gb in total). Best performance comes with ethernet connection. Wi fi connection is not reliable. Stable perfomance. Crashes are rare. You can reboot within 35 seconds. The box control works fine but it is not an air control. It gets the job done but sometimes you need a mouse. The box is the absolute streamer. Highly recommented by me.
