Installing the AE3000U was a bit tricky at first. The problem is, if the projector's mounting holes are too close together, the four adjustable feet can interfere with each other, making their installation difficult. (It would be nice if the kit also included two extra short legs instead of four long ones.) The trick is to adjust the legs to their maximum height to get the best spacing. Anyway, it works great and looks like it will work with almost any projector. I chose this brand as I already had a dedicated (non-universal) RPA mount installed for an older projector. So when I got a new projector, I only had to replace the interface board, not the entire bracket.
