I purchased this TV last 2 months ago firstly its gives a best sound and picture quality and alao have best usb easily connect but approximately after 1 month there performance going down. Its USB not connect properly with tv.
And it also gives very badly sounds. There sound not good for baby child because its provide harmfull effect in there hearing.
Second is that, its give bad picture quality. And sometimes there picture quality like SD.
This is last but not aleast so I can say that this product is not best but low good.
