Let's start with the models. 18 Eighteen is packed with teenage teases. Most appear to be from 18 to 20 y/o teens and fresh out of college. I did find quite a lot of first-timers in there as well. Overall, let's just say that if you are into flat-chested teenies with perky teen nipples, you will love the girls of 18 Eighteen.
Action on the site ranges from prom queens stripping and masturbating to college sluts taking it in the ass. There's a fair amount of hardcore scenes in there, but most of the content focuses on girl masturbating and toying (vaginal and anal).
I was pretty impressed by the quality of photos found on 18 Eighteen. Even the stuff that goes back to 2000 is hi-res... Not a lot of sites can say so. The thing that struck me the most about the photos on this site is that the guys at 18 Eighteen really know what good teen content is. The angles used in the shoot are interesting and exciting, and the setups and accessories are great. I'd say that the pictures on 18 Eighteen are different than what you will find on other sites out there, and that is a definitely a plus. Each set comes with a short bio/story to get you in the mood.
The videos on 18 Eighteen of are good quality overall. The latest are very good, not DVD quality, but enjoyable in full screen mode. As with all sites with older videos, you can expect the older content's quality to be lower. Unfortunately, the navigation system setup in the video section is very confusing. It took me quite a while to figure out how to find videos in there. It's sad because this site has a lot to offer, but the "pretty" design takes over functionality in this section. Don't get me wrong, there's a lot of great videos on 18 Eighteen, but they are sometimes hard to find within the site...
Speaking of navigation system, the one used on 18 Eighteen takes a bit of getting used to overall. The site's design is a bit outdated and is optimized for users with 800x600 screen resolution. So, you guessed it, thumbnails are a bit small and the whole site just looks a bit akward for users with larger screen resolution. I did like the layout used for galleries though (screenshot #2). When you pick a girl, a few other teens from the same issue will pop up at the top of the page... I've found a lot of fuckable teens using this feature. The search engine could use a few more options, but it's a great way to find teen girls with specific assets.
In conclusion, I'd say that apart a few navigation problems, 18 Eighteen is an excellent spot to find adorable teen girls in high quality photos and videos... The site's design could use an overhaul, but there is so much good quality content and beautiful barely legal cuties in there that it shouldn't stop you from giving 18 Eighteen a try.
