Really a must buy with a video optoma hd131X. Initially to do in the economic I opted for dlp link glasses, but after I finished my installation (projector on the ceiling, projection screen on the wall) to a 3D glasses dlp link that désynchronisait all three minutes, was exaggerating watch the film standing order not to lose synchronization. Little explanation: the projector from the ceiling and the projection screen on the wall that there was an image Décallage, I do not know if I'm clear but overall the video is higher than the screen so there more synchronization for glasses dlplink requires that the projector is facing the screen to have no signal loss. So if you like me to put your projector on the ceiling invest directly in an ZF2100 kit because the, but happiness you can be in any position not even facing the screen and the magic happens. No desynchronization and huge plus not to forget, a contrast cry from the dlplink technology. With dlplink glasses darkens the color of the image at the time of synchronization while with ZF2100 you forget the glasses so the contrast is not altered and the glasses are lightweight.
Finally as positives for this technology ZF2100 to buy eyes closed (not forgetting the need to speed transmitter to synchronize the glasses) so when looking first purchase vote if there is the included transmitter
