The mount seemed to be exactly what I needed for my dual monitors. Since the anchors and screws provided were for concrete, we went to the local hardware store and purchased anchors and screws appropriate for a drywall mount. There was NOTHING in the instructions that said a drywall mount was tabu. It only said that the provided anchors/screws were not to be used for drywall. However, the installer did comment that the mounting plate had a particularly small footprint for the weight that it needed to hold. The mount was installed, the monitors attached and all seemed well. Five minutes later the entire mount pulled out of the wall and mount and monitors fell flat down on the desk. Fortunately, since there was nothing on the desk, there was no damage and the new monitors seemed to have to survived just fine. Needless to say - the mount is not being used. I think the design is great (except for a very small mounting plate) and I'm very disappointed that I cannot use it since I have no concrete walls in my home. I REALLY THINK YOUR DESCRIPTIVE MATERIAL SHOULD POINT OUT THAT ONLY CONCRETE (OR PERHAPS SOLID WOOD) IS SUITABLE FOR THIS MOUNT. Very disappointed.
