Review on Mount It Dual Monitor Desk Mount, Height Adjustable Arm for 32 Inch Screens, VESA 75x75 and 100x100, 20 lb Capacity, Black/Silver (MI-1772) by Dakota Afzalian

dual mount arm works as expected with two 22" Dell monitors. I had to use hex screws to adjust the tension so the monitors could be adjusted to the correct height and stay in place. I've had no trouble getting the necessary tension adjustment with a hex wrench, and I'm not particularly strong. We didn't use a clamping mechanism so I can't comment on that aspect of the design. My husband made me a metal base because the back of the table is not accessible. The VESA aspect of the mounting brackets worked great with the Dell monitors and I was able to complete the entire setup myself without my husband's help (once he made the metal base :-)). Cable covers are an added bonus to keep cable clutter to a minimum. I like to have one monitor in portrait mode and the other in landscape mode and that is easy to do with this device. The only complaint I have is that the locking mechanism for the VESA mounts is just loose. I tightened the screws on the VESA mount myself and that helped a bit. Not a big problem and not big enough to give a star rating.
