I have purchased this TCL 4K UHD LED smart TV few months before but when I used it I am not satisfied with this product. First thins is, it picture quality is not too much good even on 4K resolution. Also its sound quality is not good, it’s speakers make some cheap sound in between. This LED TV is totally worst and does not valued for money. So guy’s if you are thinking to purchase this LED TV, then I will not recommended you to purchase this, as you will fully loose your hard earned money in purchasing this worst LED TV.
