using different devices (PC, shield, Pi, etc...) and pretty much same results

all sports/games available but the quality varies. at best i've seen some baseball games hit around 720p, but for the most part most events are a bit grainy, stutter and always buffer.

PPV events (UFC, Boxing) usually work decently early in fights then by the later cards when more people are presumably accessing the quality dips and it's tough to find a solid stream.

that said i use it all the time, but don't expect 1080 quality games, or many HD games often. it's cool if you want to cut the cable but not good if you're hosting sporting events at your crib if that makes sense.
