It was broken and flimsy. Advice against this product.

This is my 2nd such monitor stand from Monoprice, and it is actually an improvement over the original one I purchased 2 years ago! It's solid and easy to install.

I have a bevel-edged desk so free-standing was the only option for me. It was more expensive than I had wanted to spend initially but after just 2 days I no longer had any doubt it was worth every cent. Seamless vertical rotation allows for me to speed through tasks I had to struggle through before.

Even with only mounting two small 20" monitors I had to weigh the stand down to keep it from falling forward

Holds both monitors very well

Mounted 2 Dell monitors. They were sell within the limit for weight.. The instructions could use some change. The end pieces must be taken off to insert the mounting plates into the arms. the mounting plates for ease of installation should be test fit to the monitors so to make sure you have the spacing correct to allow mounting the monitors onto the bracket once you've placed it into the arm channel. The Drawing in step 3 shows the bracket with the solid mounting plate located on top. For ease of mounting I placed the slotted part of the plate at the top. The Lock Collar mechanism is weak. It is easy to misalign the threads and the weight of two monitors allows it to slide down the pole. I found I needed to add painters tape around the pole in line with the locking collar to keep the arms at the height I wanted. Locking collar no matter how hard I tried would not engage its threads uniformly, they are just to wide apart to prevent binding as the collar twist out of alignment as you tighten it. Other than this it works great.

Does the job. I'm impressed with the balance. Maybe I assembled it wrong, but I'm not able to raise or lower the monitors without getting out the hex wrench. Ideally I would adjust the height each time I switch from sitting to standing (the height that works for me while sitting is a little too low when standing), but instead I had to find a compromise height that works decently.

Other adjustments (tilt, etc) are easy to use.

Good value, easy to assemble, sturdy. Ready for work from home.

I ordered two of these, one works flawlessly. The other, we can't get the monitors to stay at the specified height, they just keep sliding down the pole. I instructed the other user to not touch the monitors so they don't slip down.

Would not recommend this product. The adjustability of this arm is very difficult. Even after tightening up the bolts it is still pretty flimsy. Very bulky and heavy but oddly enough not the sturdiest design. I use to 24 inch widescreen monitors.
