||It is an exceptionally good network, with gorgeous European girls, good locations, lots of content, and almost all actions I can think of (excluding BDSM and extremes like pissing).
Network allows access to several sites instantly, and more sites after the first month. Amount of content is huge, network has thousands of models and scenes. If counting updates not for one single site, but on the whole network, it will be several updates per day.
Girls are mostly from Europe, and I like it. Almost all girls are "pro" type, from 8 to 10. Locations are very good (but I'd like more outdoor stuff). Most of the girls look eager to have sex. Network provides sites with a very wide range of actions, from lesbian to anal and occasional "ass to mouth" and "ass to other girl mouth".
Video quality is great, recent videos are 1920x1080 (and look very good too). I have never seen any DRM.
Download speeds are very good for me, I have never seen any download limits.
If I could join only one site in my lifetime, I'd choose 21sextury.
