I have purchased this product 3 months ago and I have some good and bad review on its performances.
Firstly, the picture quality is Awesome. It works best on 1080p. We can download and install apps on this tv. We could transfer apps, files, images, videos directly through Zapya. We can use pendrive and external drive through its usb port. But there are some video formats where we could not hear any sound.For that I recommend vlc player or mx player. One most important thing that you should consider while buying this tv, is its sound quality. However hard I tried with the settings, I am never satisfied with its sound. I had to purchase a seperate speaker so that I could watch good quality movie. The price is higher as compared to its all round performances. I recommend this TV if could afford a seperate speaker. Overall, its performance is good.
