||I joined this site on a full trial and was surprised to find that I also had full access to all the other sites on the network (there were about 10 in total). Each of these had a fair amount of videos (up to about 150), but these were only available as full-length scenes, with no smaller clips available.
The navigation was pretty poor as you could only see what was on offer by clicking on each page individually (although there was also a performer drop-down menu at the top).
All-in-all, I would recommend taking advantage of the full trial while it's available, but I would never join for it's normal membership price. Beware of tickboxes when signing up, however, as I was automatically signed up for a free membership with another site, which I didn't even find out about until three days later.
