There are lot of negative threads on forums all over the internet, most of which are from 2014. I didn’t find much recent but I did go ahead and subscribe and I don’t see any issues. I think it is perfect for what I am doing and they have a lot of types of content that videoblocks doesn’t have.
I realize they may not last long but if they last 3 years I would spend that money anyway with vb, if they last a shorter period I will still have downloaded more than money’s worth.
TY!
