I am using airtel dth tv for more than 6 years. I am not facing any problem except weak signal in bad weather. I am from uttarakhand and I am using it in my village, which is hilly area. I bought it from local dealer. As far as its monthy packages price concerned I find it quite overpriced compared to tatasky or dish tv. But its alacarte service is good where you can choose channels. Customer care service is good. I have simple dth not hd I am satisfied with it. I am using 366 rup/month package.
Well I recommend it although it is little bit pugnacius with bad weather but it wont bother too much.
I hope my review will be helpful for you.
Thank you
