It's basically a sports (NFL, NBA, UFC/Boxing PPVs, MLB and NHL) streaming site. The NFL package is $45 total for new users; for the last ~3-4 years, I've been locked in at the returning user cost of $30 per season.
The NFL package gives you access to live games + the recorded one as soon as it's available, which let's you watch either the full game, condensed version, or the all 22 / coach footage. They also have games going back to 2012, if you're into that sorta thing.
There is an All-In-One package for $65 where you get access to all streams up to February 2022.
Here's a screenshot I took last year of just random NFL games.
