I buy this mount base on a review by someone who say that he have have the same projector that I have -lrb- Epson 8100 -rrb- . I use this as a wall mount in the back of my room which I be tell I can . the mount should be gear drive as it slip because it be a smooth connection . the set screw do not hold it in place as they should , it still slip and the projector rest against the wall . I have have to readjust my screen to fit the configuration that this mount have decide for I . it state that it will hold projector weigh much more than mine but it will not even hold my 18lb projector without slip . I do not recommend this mount .
