It's a bit basic and clunky but it does work. For my Optoma HD200X, the arms that you can see spreading out in the picture are far too far apart and I had to make them all point inwards - but they do fit the Optoma. I didn't have to make any changes to it. The mounts on the projector are only M3, which makes it feel flimsy, and if the arms were extended as shown in the picture, I'd be worried about the amount of leverage applied to such small screws. I have to confess that at the moment, I'm checking the mounting every week for evidence of any movement. Looks smart enough with my projector although the large circular plate was damaged on receipt. Other reviews I have read suggest that many mountings "creep" - I haven't had a problem with this.
