Review on Cmple - Universal Adjustable Ceiling Projector Mount: 360 Degree Swivel Rotatable Bracket for Projectors up to 22lbs (Silver) by Michael Hudson

Regarding the lever: the supplied hexagon socket mounting screws did not go in easily. The supplied wrench does not fit well as it is a bit too small. it keeps jumping out of the screw head. the use of security screws was superfluous. A more serious problem was that the "universal projector mount" included in the kit could not reach all of the mounting holes of the ASK proxima projector. Also, the projector screws were too long: we had to put extra washers under the heads to increase the length. Finally, the peg from the ball/socket that holds the projector, although so tight it was immobile when fresh out of the box, has softened and will not hold its intended position if a 12lb projector is loaded.
