I like it, quality will depend on your connection it might go from HD to SD and back to HD. You can watch any team on there with exception to CBSSN games and I think certain Denver games still. Not sure if you can start at the beginning after a game started (never tried). NCHC will also show women's games too, if you want to watch them play.
You can also PiP and have 4 games up at once.
