Finally ... after 3 orders, 7 private purchases and countless tests - these glasses are perfect for anaglyphic representation. You sit comfortably and is made of lightweight plastic. Certainly no high quality production but you carries the thing not daily. No complaint and clear anaglyphisches See for movies and in my opinion for professional applications recommended. The price was even cheaper than the other useless spectacles which I ordered. Thumbs up for dealers and product. Any time !! ;)
