I am using the Tata sky dth from last 9 months and I am happy with the picture quality.
Installed setup in quick time as soon as booked.
Really felt like no need to question about picture and sound quality.
Prices of channel packages are reasonable.
Its easy to top up our account, and easy to add channels by just giving a missed call.
Got a remote with good quality and working as per the instructions.
Customer care service people are very co-operative and helps in resolving our queries.
Only negative I felt is HD channels are pretty costly.
