I have never used League Pass so I can't compare it to LP, but I can compare it to free ad-filled streams such as adthe and vipbox. The ad-filled streams cannot compare to BallStreams. The quality of BallStreams is absolutely beautiful. I view the game on a 130inch Projection Screen and I can see everything clearly without having to worry about lag or shitty quality!
They do have a preview which you guys can check out, and I can assure you that the streams are exactly like quality of the preview, if not better.

They have on-demand for every game, which are available either the day of or the day after.
Only problem I can see with people using this service, is if you don't have fast internet to be able to stream in high quality. Other than that I do highly recommend this service compared to those who are using Adthe or Vipbox!
If someone knows of a convenient program to be able to record my screen and turn it into an animated gif, I can show you guys a sample of the Cavs game last night.
I paid before October so I got the service for $60, but I definitely would have paid double that for this type of service. Best part about this, no blackouts!
