Didn't realize it would be cardboard, but functions well and has held up fine for the first few months. Seems to be sturdy under the weight of my small monitor.
The only downside is the plastic clamps if they were metal this would be a perfect product. Not sure if the plastic will fail or break in the future. Update after almost 2 years the mount is still perfect with no problems at all. The heavy steel the mount is made out of will last a long time.
