Works for My monitors.
Seems to be well constructed but my monitor I have is kind of curved on the back so when trying to set it up it did give me a bit of a trouble configuring it, still I was able and works just fine.
I'll say it again, if the monitor is non-VESA and needs an adapter, that's a monitor you shouldn't be buying.
The rest of the job is adjusting and making sure the boots grab enough of its part of the screen not to slip off and that all the bolts are tight enough so the screen does not slip out of the mount and crash on the desk or stand.
You don't need to make it extremely tight, just deal with the slipping until you get every arm where you need it and are ready to mount.Not a big issue on their end, but just wanted to note that since the top of my monitor is much thinner towards the screen than the bottom I had to slide the clamps up just a little so they are still holding the monitor but not blocking the screen.
My biggest complaint is that there is no way to hold the screws in the center with the monitor in place.
Also they scratched the crap out of the back of my monitors because the bars covered up all of my power and display ports, so I had to move them around to compensate for it.
But it is not fit my 27 inches aoc monitor (Almost drop my monitor) .
And The Ledges so big it is cover my screen make it looks very ugly.
I decided rather than return it (and the arm I bought to work with it) I'd "make it work."
