This monitor mount is amazing! It has doubled the amount of monitors I have on my desk because I am not able to use the space above it. My primary monitor doesn't have the VESA mount but I had two older monitors that I wasn't using and I decided since I had the extra outputs from my video card I would use them also. One of the monitors I am using, the screws were too long and I ended up using some washers to make a tight fit, but other than that it was an easy setup. I am currently using the extended arms to get my monitors higher above my previous two monitors and I was able to adjust their hight pretty nicely with the included tools.
