I purchased this android based TV few month back. Its picture and sound qualities are very good. its AIR mouse facility is also very good and this allows you to directly select/click anything and it also have small key board on back side for typing and web browsing purposes.
All main applications(U tube, Netflix etc) with google play store are also available.
LED back light can be kept at your choice, overall I found this as very good TV with lowest price among all.
