I'm using this to mount an older SyncMaster 191T above my desk and was pleasantly surprised at how sturdy it is for the price.  Installation was simple, though I used the screws from the original monitor mount for the plate attachment, as none of those included would work with my monitor.  The tilt mechanism requires loosening a bolt and then adjusting the monitor to the desired angle.  I would have preferred another 10-15 degrees of vertical tilting capability, but what is available will be fine for most applications.  I posted a couple of photos that shows it mounted.
