    Had to fiddle with

    Works well, but had to fiddle with the clamps a bit longer than expected. Screens now move okay, just wish it was faster to adjust.

    Nice to have all

    Nice to have all my monitors on one post, love the extra reach. Took a bit to get the arms balanced but works great now.
