Great for single monitor plus side display
I bought the dual monitor arm intending to use with a single monitor. It works well. I use the other arm for an iPad with a VESA mount. My only gripes are a) is the screws provided for the plastic VESA brackets were not long enough for my HP monitor so I had to use longer ones, b) the vertical height adjustment is NOT spring or gas supported so you need to be careful when raising or lowering. I found a happy medium for sit and stand use that means i dont need to adjust, but this was not my original intention. Best part is now my monitor is off the desk making more desk space.
