The glasses themselves are alright, but magenta-green color combination is probably the worst of the three available (red-cyan, amber-blue). Even though they have higher image brightness and a bit wider color range, compared to red-cyan, they also have too noticeable crosstalk between left and right eye to enjoy the picture. Either buy red-cyan for near-perfect 3D effect with limited color range (in Dubois mode) or amber-blue to enjoy wider color range (albeit with some color rivalry, especially with yellow-red colors)
Not the best color separation. I recommend HBS02 model.
