Okay you may not agree with my review but for companies like Tata Sky every person has their own opinions as service may vary from state to state and person to person.
Now coming to the quality of viewing the HD quality and the Standard quality is almost the same and you hardly notice any difference so now you know what the quality of Tata Sky is.
.Service and support is too time consuming+ costly and being in a middle class family you may not like the service cost it levies on its customer even your setup box is in warranty period they charge you 250 for coming to your address.
Tata sky packages are the costliest comparing it with any connection+ the installation charges are heavy and you will only receive only 1 month free SD channels(while other companies provide 2 months SD+ HD channels).
So if you can but different connection than it will be better than Tata Sky.
