We received the mount quickly. I was originally going to use the clamp mechanism, but then decided that the grommit mount was best for my application. My desk didn't have a grommit hole, so I used a spade bit in my drill to drill a hole in the appropriate place. It all went together and while I'm still tweaking the height and angles, I have infinite options of customization available to get it just right. My dual 24" monitors should make my job much easier to do now.
