Have ordered without great idea because of the good recessions glasses and am very disappointed. If you 1.mal a 3D projector uses and so do not know what is important. You simply have to try and make his experience. The glasses are working properly and without problems. Have an Optoma projector Hd 141x and 3D work with these glasses really very good. Of course, the glasses are of high quality not as good as that of a different price category, but that's not the problem. The glasses are very small or slim fit on the display, so that unfortunately in the lower viewing zone sees the normal image and interferes in the long run but enormous. Also find that the glasses on the nose very oppressive and a longer look without constant glasses up and deposed impossible. Good thing my friend has a very thin face and yet fits your glasses well. Unfortunately I can not recommend these glasses and can only advise everyone to be careful when buying a pair of glasses that the field of vision or the glasses but has relatively large glasses !.
