mount it for a fraction of the price.

Excellent and well-constructed bracket for the price. Easy to set up so it fits my projector

It is absolutely worth taking the time to get the bracked mounted in the perfect position using a horizontal plumb line to get it dead centre in the room, but the bracket does offer enough adjustment if you're very slightly out in terms of direction - it swivels and twists giving three degrees of movement. A reasonably sturdy set of screws then allow you to lock it pretty much in place.

Money well spent.
