These glasses were an impulse purchase. You will not get the 3d affect like in a theater and it is not the fault of the glasses. The bigger the screen the better the 3D affect. The picture on my computer was a little better, maybe due to my video card having a 3D option. Flesh for Frankenstein 3D was OK, I saw no difference in Piranha 3D. Just depends on the movie. Not the best nor the worst impulse purchase I have made.
