this be my first projector mount , and will likely be my last . I be very hesitant to install a mount to begin with , my handyman skill be somewhat lack , but I really need to get my projector up and out of the way . I use this with a Epson 8350 . install the bracket onto the projector be a breeze , as be install the mount into the ceiling . the fine tuning of the positioning of the projector in the mount take a little time , but only because of my `` OCD '' . the adjustment screw hold the projector firmly in position and I have have zero issue with vibration or have to re-adjust the mount . for the price , this mount simply can not be beat imho .
