Perfect complement for a sit/stand desk!

I bought this monitor arm at the same time that I bought my sit/stand desk, which enables me to easily transition from sitting to standing. This arm makes it very easy for me to move my 24 monitor up and down when I change positions

- Read the instructions and spend some time adjusting the tension.
- Be careful about how you adjust the tilt/position of your monitor! In my case, I was grabbing on the side of the monitor and moving it around until I realized that I was putting pressure on the center of the monitor from the mounting bracket. I had one monitor stop working, which may have been due to me repeatedly putting pressure on it.

- Very sturdy design.
- The tension can be adjusted to ensure that it stays in place when you move your monitor
- Clean and modern look that goes well with my white desk. For some reason it makes me feel more relaxed when I look at my desk setup and dont see cables or a clunky looking monitor stand/arm

- Expensive! For some people, the nice design of this arm may not be worth paying 4 times more than a cheap generic arm.

I had a particularly difficult mounting situation for 2 Apple

I had a particularly difficult mounting situation for 2 Apple TB displays on an Argosy studio console. The bolt-thru option provided a solution requiring the least amount of modification to that console. I wish I would have found the M8 earlier - it would have saved me time and money.

Great for large monitor on a recording desk

This is the only monitor arm I've found that can actually support my Dell 3007WFP (30") monitor. It would be overkill for a lighter-weight monitor, but for this application it's the only game in town.

Setup was easy, adjustments were fairly self-explanatory. Would be great if Humanscale did a video explaining some of the adjustable tension points, though; printed manuals can be pretty hard to follow when describing three-dimensional concepts.

I'm frequently moving the monitor back and forth and up and down over a Mackie d8b mixing console. I would be thrilled if the arm was a half inch higher so the monitor could clear the back of the console, but it's close enough that I can always get the monitor back and high up above the level meters or pulled low and forward so I can make the most of my screen real estate.

Would be so great, if only

A great stand all the way up to the monitor mounts. That's where this monitor arm really falls short. It's really a shame since the rest of the arm is so nice. I have both the single and crossbar mounts on my setup, both have the same issue...

There is so much play in the slide on VESA mounts that the monitor(s) move all over the place. So whenever you grab the edges of the screen to move the monitor the mount flexes and twists all over the place making it harder to move and it feels like I will break something. If you have the dual crossbar (I have both the dual and single mount) the problem is even worse since both monitor mounts flex. Once you get done moving the mount, you have to align the monitors again. (like a crooked picture frame).

I really really want to love this monitor arm, but I can't believe that such a nice product has so much play in the mounts. Knowing this issue, I would have a really hard time dropping this much again.

UPDATE: I am a little happier now that I have taken the mounts apart and tightened them. It seems like some of the play was from poor assembly from the factory. I also made a few small modifications to try to reduce some play that has helped. I am still not 100% happy, but the small changes I have made did make me feel better about this purchase.

Works reat!

Works just fine for me. I need to sit close to my monitor due to my macular degeneration. This puts it right in front of me.
