Excerpt: Purchased this mount for my BenQ w1070. I love the 360 degree capability but it lacks tremendously in instructions for assembly. It comes with 4 bars that are to attach to the projector by 4 screws. Only problem is the w1070 only has 3 screw holes. It required some ingenuity but eventually I got it to work. Also the hardware is a bit cheap and depending on your projector you may only need half of what's shipped.
Excerpt: This is a well designed and a very good quality ceiling mount. Came with good instructions and worked out well to setup my BenQ W1070 projector. I did not have to use any extension rods since my ceiling is only 8 feet high. What impressed me most: the adjustments that this mount allows you [after installation] to finetune your projector position for aligning picture on the screen.
Pros: Easy To Set Up, Easy to use, Small Footprint
