I have two ACER 22" monitors and purchased two of these primarily to raise them up high enough to fit my speakers underneath. The packaging states that they work for monitors up to 20", but they work fine for my two displays. The fit and finish is good, the adjustments work great. The only problem I have is trying to get the display level if I move it around ... not a real problem, just like trying to make sure that pictures mounted to a wall are level.
The packaging includes the VESA adapter for VESA 100 display mounts. It also includes a selection of hex wrenches ... all you need to add is a phillips screwdriver. I am using the "clamp" mount and it does a find job of holding the stand steady.
