Adult 4D claims to be the world's first adult 3D site to offer HD quality. They use stereoscopic images to achieve their three dimensional effect and the scenes here offer hardcore as well as softcore solo action.

Adult 4D is cashing in on the 3D fad, but it got into the game early. The site has been online since 2009 and has been working hard to build up a collection of pretty unique content - all in three dimensions. They recommend you download a special movie player to get the most from the videos and provide a link to it - there were only versions for Windows computers though. If you're on a mac, you're screwed. The action in the movies varies from solo masturbation to all out hardcore fucking, including some anal scenes with deep penetration and messy cumshots.

As promised, HD options are available. They come in up to 1080p HD settings as Windows Media downloads. There were also non-3D downloads in the same 1080p HD settings. These scenes varied in length, some are short, some are as long as DVD scenes so around 20 to 25 minutes. According to the site its all exclusive content.

There were a total of 30 videos online. For 11 of them you also get picture galleries. These were large, high resolution photographs that looked pretty fantastic. Sets were often very large, over 200 images, and could be browsed through online or downloaded in easy to grab zip files that are provided.

The site is easy enough to get around but a little cluttered. I liked that there is a FAQ section that should get you up to speed quickly on what you need and how to best enjoy the 3D porn, essential knowledge for those new to the 3d Porn scene.

Updates are made weekly to the collection so the site is growing. Thats a good thing as there really aren't any extras included and not much else to keep you busy besides the video and pictures online already, and it shouldn't take too long before you go through all of it.

Adult 4D is definitely a novelty, and so its unfair to look at it like any other porn site. It offers a rare product, 3D porn, and it does so in HD, which is even rarer. If that's what you're after this site delivers and is worth joining, even though it isn't large and updates at an average pace. Some bonuses would have been nice, but it will work out without them.
