Excellent product; mounting structure a bit confusing

by Michelle A, Florida, May 08, 2015

We purchased three of these monitor arms for three monitor mounting. It works just as advertised and we are very pleased with its structure. However, the mounting structure was a bit confusing. We ordered the base grommet mount style (none of the additional hardware options were needed). When we got them and the tech installing them was clipping them to the back of the desk, we realized that technically you could use these for a grommet or for a back of desk install. They have the plastic lip around the base to fit a grommet, but in the event your desk doesn't have that, they still function okay. I guess that was good since we were told our new desks would have grommet holes, when in fact they don't. All in all very satisfied with this product.
