Difficult to rate. The actual lenses are superior to anything else I tried 3d, tried both on my Sony TV and cinema, and there really is no overlap compared to other shit I've tried, including the ones you get at the cinema, however, the design is useless. The glasses come off, and the arches are gone from the hinges on both. Got glue with superglue, so now they go not to fold.
Will test the Polaroid now, they have proper arches. Will return here depending on how they compare to the polarization.
