I've got a question that someone may know the answer to. The price of the glasses turns me off too, so do the glasses from the theaters work at home on a 3D TV? The last few times I've gone to a 3D movie I went during a weekday matinee and barely anyone was working the theater. I walked out and no one was near the dropoff box outside, so you could just walk out with your glasses freely. I didn't know if they were any good at home so I tossed them in anyway. Just curious. I know they feel light and cheap in the theater, and the ones at BB on display were heavy and battery operated. Any real difference?
