I am the user of tata sky from around 2.5 years . The picture quality of it is HD and it remains the same when the weather condition is dark in cloud. The sound quality of tata sky digital tv is ordinary like other digital tv. The services given by tata sky are very useful like jingalala saturday offer where we get some offers every saturday and some other features like tata sky mobile app by that we can see tv even if we are not in home. IN tata sky we can record shows and play whenever we have time this is the speciality of this dish tv. The support of tata sky is 24x7 when we have queries we can solve them by calling on toll free number of tata sky and the additional option is online chat in which we chat the tata sky executive for any queries to solve on tata sky. we can also change the pack online and pay money to them online by removing money by debit card.So this digital tv is much more advanced becase the system is updated every month.At this time this digital tv is at no 1 seller of digital tv in INDIA.The value of money is much motre taken into account by them . So this is very good digital tv and I personally suggest this digital tv. If you like the review please like it.THANKS FOR WATCHING.
