First, The I-Theater works...It connects to your Ipod (With the extra A/V cable from Apple), it works with Game Consoles, I tried it with the PS2..not bad:
Here are my thoughts after one day of using it:

Construction and Quality:
**
Two Stars...The Stems on the glasses are really cheap..like a toy. For $300 it should be much better...In fact, I think that that is a major drawback to this unit...it does not feel like a $450 technical wonder. I was hoping for more metal frame, but I guess they needed to keep the weight down for comfort They should have put a little more into the Quality here.

Performance:
***
The video quality is quite good! I can't fault its performance. I was also afraid that I would not be able to see through these correctly, as I have a condition with using both eyes at once, and I wear Trifocals ("Watch for me on the road ;-)..Mr McGoo")
But I had no problem wearing these, it worked great!
Now, it works best... Read more

This is a fairly good product. I had no problems getting them to work with a cable tv, dvd, or ipod. I think something may be wrong with the cables for the dvd connection because one eye screen is darker than the other, but when I connect it to my ipod, which uses a different cable, the images are the same.Another problem that I see with them is that they do not cover your entire field of vision so it can be a little hard to concentrate on the images in the glasses. Using them in the dark eliminates this problem. Also, you have to be fairly still when wearing them because the slightest movement will cause them to lose the picture if the connection cables are jiggled. Also there are alot of health warnings that come with the glasses about wearing them too long. The picture and sound quality is good. Not sure if you can tell how big the screen looks, but it is a nice size.
Overall, I would recommend this product, especially if you do alot of traveling or want to watch a movie in... Read more

I ordered these glasses with some reluctance because years ago I checked out those big bulky helmets with CRT displays and was still kind of harmed by that experience. Times have changed yet, and these glasses are not at all what those old HUD devices were like.
The mechanical quality is fairly good, the braces that go around your head are made of elastic plastic so it's more like putting one of those cheap sunglasses on that squeeze your head but I suppose that is to give it a firm grip and prevent the weight of the device from pulling it off your nose.
That said, the video quality is astounding. After you manage to set everything up and set the video output correctly (I only connected it to a computer so far, so I don't know about other devices) the picture is brilliant and clear. The built in earphones also give a fairly good sound, so all in all, I can't complain and would buy them again.

Two caveats to look out for (maybe it's just because I am not a whizz... Read more
