I have been using my tatasky dish antenna for last eight years. Earlier I heard its name that it gives good picture and sound quality.
Now after using it for so many years I can say tata sky is really and reliable.
It gives all updates time to time.
Its customer care service is also good. M satisfied with it.
You can use tatasky .com to upgrade your channels. It can be little costly but satisfies.
But its good value for money you can say that.
