I got this LED yesterday and so far my reviews are:
Pros:
Built in google apps including playstore so you can download any app you want very easily.
It has both android and patchwell so you can feel the customized features that MI has put in patchwall at the same time you can avoid the disadvantage of patchwell like unavailability of play store, lagging screen casting etc.
8 GB internal memory out of with you will get 4.3 GB for your use remaining is already occupied by android and patchwall.
It supports bluetooth which will help you to connect your Bluetooth speaker.
Remote is also Bluetooth connected.
Cons.
Defaul
Default color setting are little fade but I customized it from settings.
They won't give wall mount and remote batteries in the pack so you'll have to spend more than 400 above the base price of LED.
I felt LED stand is not that good.
Overall product is worth its price.
