Review on Optimized Four Monitor Mount - Freestanding Standard Monitor Mounts by Amy Cook

I was afraid my monitors would break when I first saw the product, but it's durable. I brought the standalone version. It sits on my desk, behind a shelf, and against a wall for extra support. So far so good and I often correct the angle with no problems. The instructions aren't the best, some diagrams and steps are incomprehensible, but I figured it out. I assembled it myself, but a second person helped me a lot to mount the monitors.
