They work as advertised but I'm not thrilled with them as the case for them is thick and bulky and keeps my glasses too far from the 3D lenses making them less than a great 3D effect as the frames The 3D glasses themselves are always visible when watching a movie. Neither I nor my spouse rate the weight of the glasses; Since we both wear glasses, the added weight and bulk of these DLP-Link glasses makes the whole experience less than good. But for sheer functionality, when watching Avatar 3d or Jurassic World 3d, they're fine. I did find that I had to adjust the color settings of my projector and viewing software to improve color saturation, but otherwise the 3D effect was very good. some guys filming in Jurassic World) ran across the picture, but of course this effect is not related to the function of those 3D glasses, but rather to the 3D TV and the projection of the 3D house. [I seem to recall that the Avatar 3D commercial theater is noticeably better in this regard, but I assume that a commercial theater might use a different video frame rate than a Blu-ray 3D disc - unless it returns another variable that I don't know about. I don't know.] I would recommend that the manufacturers of these glasses move most of the frames either to the temples or to some other location that doesn't affect the comfort of the wearers as much and allows the 3D glasses to be very close ( if not level) with the lenses of the wearer's eyeglasses - WHILE THEY ARE WEARED. I find that I can put them on our table and my glasses are on the table behind the 3D glasses and in this position they seem close to 3D lenses; But when they actually wear them, they aren't that close and easily slip off our glasses and become an annoying part of our field of vision.
