Yeah, considering the terrible quality of YIFY's movie rips I wouldn't see this as being competitive with legal alternatives at all. All the audio is low bitrate stereo, and the 1080p video never goes above 2500 kbps. The second there is any motion the entire thing falls apart into a blocky mess.

Such low bitrates do make it easy to stream, but I don't think the site is correct in saying you are watching "the best quality".
