The glasses are comfortable to wear and manufacture seems in good order. BUT: the red glass is not enough saturated (too intense) and therefore, it lets the blue image in addition to the red image. Therefore, even if the blue fulfills its role, the image is execrable with fake permanent contours. After 10 minutes, there was the shower ... No movies in relief anaglyph not satisfactory, or on the big screen or on computer.
The cardboard glasses that I bought 30 years back (and stored) to see THE film in relief work wonders on tv next to these plastic copies (though the old have super fine plastic films instead of those thick plastic of today ...) Too bad. I need not return them! It also cost me expensive shipping ... A word.
Received in 8 days approx, as they come from China.
