Pros: High quality, works well, simple optics make it work.
Cons: price

The system works very well. The mirrors are of very high quality as is the slide viewer.

The adapter screws onto the front of a 50mm lens. (you cannot fudge the size by very much. the 40mm pancake will give sub par results although the 55mm doesn't seem to be a problem) and you aim, adjust the adapter which swivels on the front of the lens so you can synch the two images, then set everything else as normal.

Exposure is calculated the same as not having the adapter on. The best aperture to use to maximize the 3D effect is around f8 to f11 as the instruction says. The effect is more exaggerated the closer you are to the subjects, I have however found that the 3D effect works well as long as there is sufficient distance between the objects in the image.

Because the adapter splits the image in half, the final 3D image is viewed in portrait orientation. So that is one adjustment that needs to be made during the composition.

Slides that are produced are then used in the slide adapter. The eye pieces on the adapter have a small amount of adjustment in and outward to accommodate different eye distances. This works for most people, although I have come across a few that just couldn't focus the images no matter what they did.

In the digital world, you can scan the negatives or slides for use in various 3D viewing methods. With digital SLR cameras, the adapter works well with 50mm equivalent lenses. (35mm for most Pentaxes)

You can then post process for various viewing methods (ie. cross-eyed: swapping the left and right images, or printing for a viewer like the Pentax D viewer) Also, images can be used in various iPhone viewers like the Hasbro My3D viewer.

Its a nice toy. And despite the high tech 3D methods involving iPhones and HDTV's, a 3D chrome is a pretty awesome thing to look at.
