I am using tatasky for the past two years and I have to say that theservice of this company is hust awesome.u will definately have a good experiance with their service.
Once u install this product u have to pay for the package only u will not face any problem regarding any discommunication.
Though in rain it give problem that is normal in all company.otherwise it is very reliable.if u want to install setup box than definately have a look at tata sky.
