    Good monitor arm!
    Bought this for an Asus ROG Swift 34" Ultrawide monitor (PG348Q)Works as I had hoped, with one minor exception. the ball joint that holds the monitor is barely strong enough to hold the monitor upright. I had to tighten to the point I was concerned it might break before the monitor would stop sagging downwards. For reference, the monitor is about 24.5 lbs.Short of that, I am very pleased. Setting it up was easy.Seems stable mounted to the desk. Note that the C clamp can be wider then listed (as much as about 6 inches), but you might run some risk as it will only be held together with 2 screws instead of 4. I like that it's pretty low profile, not as stand out as some others, and the base is small and simple, nothing more than it needs to be.The star was docked due to the monitor sagging until severely tightened.
