While this site is a fake version of the original yts website, the movies are high quality. The pop-up ads are very annoying and probably malicious but if you get past them then you're good. It is probably illegal as well since all of these movies are free on this site, so just be aware of that as well. I wouldn't really let a kid on this site though because they might download something from an ad or an R rated movie.
It has legitimate torrents but the quality isn't that great. The quality of these movies, at least video wise, look like they've been taken in a movie theater. You can find similar quality on any torrent website so the website itself isn't very special. Sure it has previous YIFY torrents but you can find those on thepiratebay as well. Kind of a waste of time being here unless they bring something new and different
