The diameter of the post is smaller than the clamp the holds the two arms. Even when crimped all the way it still would not grip the post. There is not any gasket or anything provided so I had to wrap with a strip of gorilla tape to then crimp the arm down to.I would check everything works and connects properly before drilling if you plan to use that method.
I bought an open box relist for $30 6 months ago and can say its held up very nicely. Holds its position and doesn't slump with heavier monitors (My main is 16lbs). If you can get it for even $60 that is still a really great value for cleaning up cables from your desk.
I bought this hoping to consolidate the two separate (cheap and noisy) monitor arms I had been using, but I hate this contraption even more. Installation wasn't too bad until it came time to position the monitors once they were attached. Long story short, every time I try to adjust the position of my primary monitor, the secondary monitor wants to move too, and I don't have enough arms to keep the one stationary and fight with the other to move where I want it. Hard. Pass.
It will not hold the weight of even a light 32" monitor. Arma do not support the monitor.staying up for 32"Works for 27 " and smaller
This is a pretty solid monitor stand, and I think many of the folks who had trouble with it didn't do a great job of reading the instructions...For me, I have heavy monitors, that really pushed the advertised weight limit of what this mount can hold, and it was still pretty good. Ultimately, I wound up going with a higher capacity model, but for lighter screens this one is a pretty good deal.
