The monitor arm was too short for my work station.

Looks great, performs poorly
For this price point I expected something where I could easily adjust the monitor. It's either too stiff to move up and down, or it's not strong enough to support the 27" flat screen I've got. It's solid and it looks great, but I've gone back to using books to support the monitor. Very disappointed.

Did Not Work - Terrible Install
Returned one as defective, and ended up donating the second one. Simply would not work. Terrible installation instructions, for what should be a very simple install!

Hard to remove counter mount
I needed to use the grommet mount. Removing the counter mount portion was a little difficult as the screws were on very very tight. Thankfully my boss' were able to remove the screw but stripped it in the process. Thankfully we did not need the screw after it was removed. Overall I like the mount, it serves it purpose by giving me more working area.

3M MA140MB 7.5 swivel monitor arm exceeded my expectations. Very well made,good looking,holds my 23" monitor,my monitor did not have the mounting screw holes on back of my HP monitor. I had to fabricate a mount it worked well. Best if you are not very handy use with monitor that has mounting that matches MA140MB arm. Very satisfied would recommend to friend.

Won't support the 30lbs it's supposed to.
Put a 20.4lb monitor on a stand that is supposed to support 30 and you'd think it would hold it - it doesn't. I have tightened up the ball joint to the VESA mount so hard I'm afraid the bolt will snap and it still tilts down without support. Completely the wrong joint to use for a heavy monitor. Poor form 3M. I have rated this stand so poorly because it is basically use...

Depends on how you use it
We are a business that bought over 200 of these last year for a monitor and cart that we sell. We cannot use the L-brackets that come with this arm on our cart, so we remove them and insert the hand knob that's used to tighten the clamp into the base of the arm tube that mounts on top of the table. In the last couple of months, we have had to return up to 50% of these a...

Great Monitor Arm For The Price
This was the cheapest option available that would support a 32 inch, 30Lb screen. My expectations were not very high and my monitor falls at the high end of the weight support for this mount. Pros: easy assembly. handles up to 30 Lb (my display is 30 Lb and the mount seems pretty solid) Good height and extension length. Full range of motion is easily achievable even wit...
