I have a U1 and since I needed a second box I would have wanted a U9 since Minix really is a good player and the support is great. However, while browsing the net, I was able to see a 2nd hand Nvidia Shield TV (2015 version) and after some reading of various reviews, I then grab the opportunity to check the one on sale, even though its second hand. After checking the item, I paid 8.5k for it. Although it may cost more than the U9, yet I am very satisfied with the Nvidia Shield as its support is likewise great. Note that the 2015 Nvidia Shield TV has also been updated to the latest Android OS (Nougat). Moreover, it can act like a game console as it has a game controller. So android games may be played thru the game pad. There are also games that are exclusive to Nvidia Shield. By the way, when I bought it, it comes already with the game pad and a remote. Thus, I consider myself lucky since what I bought may reach as much as around 11 to 12k.....
So, for those considering getting a new android box, take a look at the Nvidia Shield TV...
