iTheatre Virtual Vision Video Glasses with PMP and DVB-T TV Tuner (38-inch Screen Effect)

Pros: They do work great for video. It's like sitting in a movie theater about halfway back. Price is great compared to other places I've seen.

Cons: TV tuner tuner doesn't function in America.
I have volume control when playing videos, but not MP3's. I found that odd.

Other: It's really good for what it is, but it's not intended to be a replacement for a PC monitor. Video resolution is only half normal TV video, but they do a great job of scaling down for the price. I recommend them.

Pros: This makes it easy to carry a monitor/TV around with you!
Offers easy to watch screen, added privacy.
Feels comfy, no eye strain!

Cons: Pretty heavy for a HMD, not noticeable and certainly not painful but there are lighter ones.
Image quality quite blurry, not HD.

Other: This is not a "virtual reality" screen, don't buy one expecting to be blown away by the image quality or clarity of the image, its just a cheap low-end head mounted display, and its quite good at what it does but most people are disappointed because from sci-fi films they have seen they expect to be in another world when they use it, but in reality its just looking at a magnified screen.
If you know this, it is a great deal!
