its great if that all you use it for.
The app is great if you just want to watch Ballys. Realistically I could get away with the Sling Blue package and the Bally's app and pay 55 dollars a month rather than the 85 I am paying now, since I normally never watch ESPN which is the only thing I would be missing in this setup. I'm going to hold off and rely on people here and some other fan sites I visit for feedback before I make a decision.
I know people here and elsewhere have suggested uzzu, but it seems like a total scam to me (if its too good to be true, it probably is).
