Very good mount with one major flaw. This is a terrific mount, and a very very good value. All aspects work well and it is very well made, with very good appearance. The one major flaw is that it has no 'rotate' capability. I do not mean that it cannot rotate between horizontal and vertical, but rather there is no minor adjust a of a degree or two, to compensate for the weight of the monitor in certain arm configurations from tilting from the weight of the entire system. Many mounts have this capability. It makes the monitor set up look klunky if it takes this tilt. It could have been solved by perhaps slotting the VESA 100 holes in the mount plate to allow micro-adjustment, or designing a partial rotate function into the arms head. Other than this, the item is a terrific mount. But it is a material flaw in design.
