I had the mounts for the bottom four monitors from another company. However, they were unable to provide a mount for my top two monitors. With the VIVO Desk Mount Extra Tall 39", the monitors could be raised to the desired height with 5" headroom. The shaft felt very solid and I recommend a clamp rather than a table stand as when I move the table I don't want it. Points are deducted for the quality of the connecting material and the difficulty I had in tightening the connections with an Allen key loosen so I could move the monitors into place I ended up getting the two monitors fairly close together, although the height adjustment appeared to only raise the monitor relative to my arm. Overall I would recommend this for Tier 3 monitors.
