Acabo de montar el brazo Onkron y, aunque todavía no he colocado el monitor, la impresión que da es francamente buena. Pero… una de las piezas necesarias para montar la base en el borde de la mesa es defectuosa, como puede verse en la foto: la rosca de la pieza en L está torcida, de manera que el espárrago roscado queda oblicuo. He obviado el problema recurriendo a la otra forma de montaje (con agujero a través de la mesa). Así pues, suspenso para el control de calidad del fabricante.

I used this for my 28" Samsung UHD display, and it worked great.If your monitor is within this mount's acceptable range and the mount doesn't seem to be able to hold up the monitor's weight, try adjusting the upward tension.At the hinge between the two sections of the mount, there is a Allen screw with a +/- sign engraved around it. Tightening it towards the + (counterclockwise) will allow the mount to hold up a heavier monitor.The instructions do not seem to explicitly state this, and it is not terribly intuitive, which is a failure of the product, but not enough for me to dock a star.I debated springing for a more expensive mount (this was 35 dollars for me), but decided to take a risk, and it works perfectly for me.If your desk is tight against a wall, and you don't want your monitor 3/4 of the way across your desk up against your nose, you can adjust the arms so that the monitor is also up against the wall (arm swivels at the base, have both segments one on top of the other)

The arm looks like its well made and was easy to assembly

I bought one of these last year for work and it has been great. I have a sit/stand desk at the office and this arm has been rock solid. I adjust it up when standing and down when seated. It worked so well that when I wanted a new monitor for my home office, I didn't even look at other brands and just bought another one of these.It works as expected, is stable and easy to adjust the tension to get it how you want. Great product, super easy to use, great quality materials, and works a treat.my ONLY complaint that kept this from being a 5 star rating is that there isn't any detent or index in the rotation head that sets you at level. As you can imagine if you are moving up and down often you may rotate it slightly. It would be great if there was some kind of 'notch' when it is level so that you aren't staring at your monitor trying to make sure it is level after you've moved it.

This is a good product and does what it says it does.Only issue is that the bottom joint above the desk mounting bracket points 90 degrees to the left and can't apparently be twisted to point straight into the desk as depicted in the assembly guide. Contacted Amazon chat and they couldn't tell me how to twist that bottom joint.Update: the unit's Amazon Seller, TVMountsTVCarts, got to me with the following helpful advice: "In order to rotate the arm of desk mount in different directions, you need to install it with monitor on your desk. And due to the weight and stability it will be easier to rotate arm." Haven't tried it yet, but this makes sense, and I appreciate their prompt response.
