No problems here with ILP, for the most part. Very good quality at 3mpbs like hgb said (though I also think they should upgrade it, it's been 3mpbs top for a few years already). At $15 last season it wasn't just a bargain, it was basically a gift, and you don't even need to keep the VPN on once you log in. I watch mainly on my laptop (usually on demand due to the time difference), but it's worked fine the couple times I've sent it to my TV.
I've been using plenty of platforms over the last 12-13 years to watch the NBA and other sports online, and I've suffered some terrible seasons with ILP, but last season was pretty good, at least in my experience.
