I have heard that these guys are good in terms of providing no. of channels, with a reception better than tatasky & also continue to provide service for few days with 40 channels, even if your bill is overdue, unlike tatasky where the service is discontinued the very next or after 1-2 day(s).
But their problem part lies in their design of navigating through their application software through TV unlike tata sky which is easy to understand & user-friendly. its said that the physical Dish life of dish tv service is of 3 yrs whereas of tatasky is 5 yrs.
