Brazzers Network displays plenty of information throughout the tour pages as to what kind of porn site they are. They state they have "21 sites, updates 3 times a day, and 30 min full length scenes". Kind of makes my job redundant, doesn't it? All the information is already spelled out for the surfer. But is it all true? Well, after browsing through the sites for a day, I would have to say yes.

Having access to 21 quality sites at your fingertips means a LOT of porn to look at. Brazzers film their own material, so its exclusive to the network. The general themes for all the sites is big tits and nice round asses, so the models tend to be more curvy than most amateur pornsites. Curvy but certainly not fat!

Each individual site is themed, and unlike many other mega sites, they could actually stand alone on their own merits, and offer reasonable value for money. I took a look at the most popular out of the bunch:

Hot Chicks Big Asses: 27 episodes in high quality video, showing off some cute round butts.

Baby Got Boobs: 126 movies and photosets, showing the best of breast. Fake boobs as well as naturals. Updated weekly.

Milfs Like It Big: Big cocks and milf combine in 16 episodes. Good quality video, the photos are only average quality.

Big Tits at Work: Again more big tit action, featuring secretaries and a general work/office theme. 70 episodes, available to stream or download.

All up there are 1458 episodes across all sites, I don't have time to go through every one, but the video quality across them is above average. One thing to watch for though are the older clips, shot in lower resolution and not up to todays standards.
Also some the sites no longer update, such as HQ Honeys, which is a shame because there is some material in there.

Overall, the Brazzers Network is up there as one of the top mega-sites. There are multiple weekly updates and the producers have a knack for choosing some really hot girls. The membership price at the time of writing is $9.95 per month, well below the average across the industry, and represents excellent value for money.
