The women were mostly very hot and very eager. The vids could have been spectacular. But the cameraman and especially the editing was as bad as it gets. To me, every ZS vid I saw was a huge let-down (I saw at least 2 dozen of them. I was to the point that I quit downloading them even when they were free.
ZS also had movies submitted by "amateures". They had disclaimes on the site stating that the "amateur" vids were of low quailty, had poor camera work and lighting. The fact is that the ZS "professional" vids were as bad or worse.
The original concept of ZS was great, the models were great, a few of the dogs were ok, but the vid production truely sucked.
