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.

I am using this Onkron Desk Mount to support my 27" HP Monitor. I was sceptical that the monitor would not be adequately supported, as it weighs in at about 22 lbs. (an older heavy model). After adjusting the support arm tension to its maximum setting, the monitor is sturdily supported and is easily adjustable to an optimum position. At present, it is holding its set position very well. I am very pleased with the construction and appearance of this monitor support arm. My monitor has 100mm VESA mounting holes

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

Purchased two of these as another model that I originally set my sight on was suddenly out of stock. Despite a price that is significantly lower than most other similar desk mounts, it is a good quality product, solidly made. I use them with 32" Qnix monitors (using an adapter plate to cover the 100x200 VESA requirement for the monitors). My monitors weigh just over 19 pounds each and this appears to be close to the maximum weight for these mounts, as I had to tighten the setting of the arm significantly, and also the tilt hinge which was somewhat difficult to tighten sufficiently to stop involuntary tilt. However for anything of lower weight and up to the 19 pounds or so mark, this is an excellent mount. It also keeps the monitor nice and high (can lower it of course), some of the other mounts don't go as high as this one (I'm tall, and did not want to look down on the monitor when sitting at my desk). Recommended.
