I've subscribed to it. I have enjoyed it so far. It's not the greatest thing since sliced bread, but it's not a bad addition or enhancement to the MRR experience.
The deal is though.. whether or not it's worth it is going to be relative to the end user. At the rate they are adding new content since launching, I am not overly pleased. And lately they are posting new content slowly, but most of it seems to be older video content that was previously posted to the MRR website. So to me, I kind of already paid to see it there.. and now I'm paying again to see it on MR Video Plus. So, that's a little bothersome.
But it is nice when they have new content.
