We use this stand ourselves, and we love it. It is a great way to mount three monitors for a triple monitor solution. The unit is very adjustable allowing you to tilt each monitor individually. The height of the horizontal bar can also be placed in multiple positions (heights).
It comes with a super heavy base to hold the monitors very steady. It also comes with the parts to allow you to bolt it to the desk, if you desire. This unit would be great to pair with our White Lightning system that supports three 1080P monitors up to 27".
