    One of the clamps didn't sit perfectly flush

    Solid build, but one of the clamps didn’t sit perfectly flush. Still, it holds everything and I can move the screens around easily.

    Hooked up four 27

    Hooked up four 27” screens and it feels rock solid. Took me longer than expected to figure out the perfect layout but worth it.

    Heavier monitors make it

    Not bad, but heavier monitors make it a little wobbly if I push the top-left one too hard. Works fine otherwise.

    Took some trial and error

    Took some trial and error to get all my monitors lined up, but the extended reach feature is amazing. Perfect for gaming and work.

    Love this setup

    Love this setup. I work in finance and having all four monitors at eye level actually saves my neck from aching.
