Couple of tapcons into the concrete and this was mounted in less than 5 minutes. There's no real adjustment to it and you would need to put one way screws into the bottom if you were worried. Cheap and cheerful solution.

Perfect in tight spaces when you want to have monitor as close to the wall as possible. Just make sure to use the monitor with cable connections that are pointing down. A little hard to put the screws underneath to secure the monitor after it is attached to the plate. Having some simple locking mechanism could make it easier but for the price it is hard to beat.
