I am using this product this is a quite decent and best performance led tv watching movies and serials in this TV is good.
But there is a problem in USB port some time when we use sometimes it's on and sometimes it's not on so why this happen I dont know that's the only problem.
And we can talk clearly and sound system is quit well. And feedback of HD videos are great and HD channel run very good which is provided by your operator and clearly is also depend on your provider. BUT OVERALL this is a great product.
