The navigation was generally fine with a really good index of all the latest updates especially being impressive, and nice categorisation of all of the content. The viewing options were good enough on the videos - there are HD downloads that will play at 1280x720px in .WMV format, and streams that will play at 640x480px for the most part via a Flash player. These were all full file versions though so you may have to endure some lengthy download speeds. The image sets are all available in .ZIP file downloads but I don't think you could view images individually. Very odd.
So, with a pretty hefty 1210 episodes behind it and new videos added around about 3 or 4 times per week, iTeenVideo.com has serious value for money behind it - as long as the content was good! From what I can gather, this site is almost like a 'Best Of' of all the other sites from its network. So although the videos are exclusive to the company you may well have seen them if you are acquainted with any of its other sites. Just by way of a warning.
For fans of European girls and younger models, you really get what you ask for here. Lots of really sexy models, many of whom could be amateurs, and lots of well shot content too. It focuses mostly if not exclusively on hardcore action as there is some girl/girl stuff if you dig deep enough. You can also find some of the models taking a dildo to their pussy as well. It's never anything too challenging but it serves its genres very well indeed.
Aside from one or two features on the navigational side that would have been welcome additions, iTeen Video.com is a really excellent teen hardcore and teen modelling site. The archive is impressively huge and as long as you haven't already invested in other sites from this company, you will find only new content here. Great value for money too and resisting this will be even more difficult for you than it was for me to try and pick my favourite girl here!
