I have been using TATA SKY DTH service of last 4 months and I am very satisfied with TATA SKY. For installation you need to register at online and it will be done within same day or may take 1-2 days. The installation process is so simple. There are wide range of national and regional channels available with good package. You can arrange your package according to your need. You can even add a single channel of your liking. Every week tata sky offers different offers to their customers as Jhingalala saturday offer. It provides good quality picture. Sound quality is also awesome. HD channels full 1080i resolution. Few days before when I was facing technical issue with my set top box I called their service & support team, and the issue was solved withing single day. I am happy with my tata sky connection. It is absolutely value for money product.
