I am using Airtel Digital TV since 3 Years
And very much satisfied with it. THE channel numbering System and service availability is quit nice and the signals capp very rarely and also even from last 3 years there is very less even negligible maintainance cost.
Pros: -
# Nice Look Of Set top Box And Remote
# The User Interface is Very friendly And Easy to use
# Customer Support Is very Nice
# Recharge are cheap
# No blind balance deductions
Cons: -
# No recording Facility is provided to me
# no mobile support
# no mira tv support
Above all I am having a great experience with this Digital set top box and qould surely going to continue with it and qould also recommend u to buy it.
