Without the installation instructions, I began to separate the parts, starting with the main base. It looks like an alien ship out of Battlestar Galactica.
There is a USB 2.0 hub in the base with headphone and microphone jacks. You can also store the Allen keys in a compartment.
The main support bar slots into the base, but pay attention that you slide it in the correct way. Turn it clockwise to tighten it into place. A plastic sealer cap can be placed on top once the main arm is threaded in.
The arms are very well made, like the rest of the product. The construction is from heavy duty metal and each of the arms can bend both forwards and backwards for fine adjustment of positioning.
