The spectacle itself is very easy. The resilient plastic temples also attached with a stubborn like me; o)
Only the glasses could be slightly larger, so you do not so much see the eyeglass frames.
In home theater with projector I DLP glasses, which are slightly larger, but they are also much harder, felt about twice or three times. But you have the advantage that the fold-down ironing are so broad that hardly any light falls behind the glasses. This is different with these glasses. Even the slightest ambient light, the environment is reflected in his glasses, so you can see their own ears or the wall behind you. For complete blackout no problem, but this is much more strenuous 3D watching, because you get tired and weary eyes, the 3D effect just goes flutes. Through visible objects in the environment, take the 3D depth much more conscious and intense exercise (which I mean no hard illumination!).
I have now resorted to the fact that I have completed each page with a folded and glued on one side of paper, I can just drag over the bar. One thing is certain white paper not particularly smart and could also use black craft paper, but even so, it is possible without disturbing mirror lungs even in daylight to watch a 3D movie. I had not even expected that it would work so well. But for about 1 cent of material costs, it was worth a try; o)
Something I find problematic the battery holder. Here is a CR-2025 coin cell is held only by 2 really small noses that can break fast at gross motor removal also. Without long fingernails or something the removal tool with sausage fingers is already not entirely without problems. If you look at the but conscious and pays something out, the glasses can live a long life in 3D ...
But what can be avoided is not likely that the latching noses of the battery cover to cancel. This one can only horizontally postpone and close. Even in this case one of the tabs is interrupted me after the third battery change. The other now seems to be under less stress and keeps hopefully some time.
