We have already secured two beamers because once the Epson 9100w 6000w TH and later an Epson TH. In both cases, a secure and good attachment to the ceiling is ensured. In particular, in the former (no lens shift) the multiple adjustment options offer home theater enthusiasts all that is necessary for rational orientation. Of course, a certain amount of planning is also here in the run condition. We would also draw to a later date to the original Epson product. (We have previously tried 2 different mounts and unnecessary sunk money). If you invest +2000 euros in his home theater, you should not try to save on such essential matters as the holder prefer. "Avarice" is by no means "cool" in our experience in this case.
