It holds the monitor and was easy to assemble. I kind of wished it had an option to mount directly to a desktop to get rid of the GIANT base.

I am very pleased with this monitor stand.  The product is as described and was easy to set up.  It has had no problems with my 23" and 17" monitor configuration.  The cable management clips perform as expected.  I found the method the manufacturer used to package all of the included screws and fittings to be novel and useful.

This holds my husband's monitor up well, and rotates out of the way when he doesn't need it, so I see no problems with it! :)

It is easy to set up, can be adjusted easily and is sturdy and holds a 23" flat screen with no problems

All I had to do was unfold it and put the desktop on. (easy setup) I was able to fit my monitor, keyboard, and tower on the desktop.

It was easy to setup and it works. Since it mounts on the rear of my desk my larger monitors don't have the same range of motion I would prefer. There is a trade off between closer to me and being able to see both monitors. As you pull them forward the monitors move towards the middle. With my 22" monitors I can only have them more than a foot from the back of my desk is to orient one vertically. It was something I didn't consider before my purchase so I thought I would leave it in a review. There are little plastic hinge covers at the joints to disguise the tightening bolts, these don't always stay in place. On a positive note the included cable management was an unexpected bonus which has really helped keep the desk clearer.

Working amazingly so far, I have two 24 inch monitors mounted on it currently and have no issues with monitors drooping or not being able to stay in place as I read in other reviews. I also wasn't missing any parts as other reviews stated, in fact it came with quite a few extra assembly parts.

Can't think of anything that would add to it, maybe if the clamp part of the instructions actually had an illustration for the other piece of the assembly it would be a little more clear which side it has to go on but I suppose that's common sense.

Looks Good on desk, brings monitor to eye level and frees up needed room.

It's a bit flimsy but if you're only putting a <20lb monitor on it you're fine.

I bought this for my home setup which features a large Dell 27" monitor as well as a Wacom Cintiq 21" monitor. Both are supported well with the mount, but can be moved easily, when needed. The hydraulics work well to keep the monitors at the level you set.

The product was easy to assemble and install, and has performed as expected. I don't think I put anything much larger than a 19" monitor on the arm at full extension, but otherwise, no problem.

Just what I needed to get my monitor to a comfortable viewing height, and to recapture the space beneath it for my laptop

Well constructed, easy and reasonably easy to set up. The only issue I had was adjusting the arms so I could attach one monitor before the other without it falling over, It's my first monitor stand, so I don't have much to compare it to, but I like it quite a bit.

I can't speak to how well it would hold up if constantly being moved as others have.  I bought it to get the monitor close to my face to compensate for poor vision and I leave it in one place.  It is designed to clam to the back of the desk, but my desk won't permit that so I put it on the side and it works pretty well.  The only thing I wish for is a way to extend the crossarm out further.  The height of the monitor is going to affect how far out it will be, so the higher you want it the further away from you it will be.  Or, in my case, the further to the left.  I had to compromise between height and position.

This is exactly as advertised, it supports two monitors and claps to a desk, so if that is what your looking forward this will suit your need.

Pros:
 Very sturdy construction, the clamp, the hinge joints and the stand all seem pretty strong. I feel comfortable with having both my  21in. monitors supported by it.
  The slid-on mounting brackets made setup super simple.
  All the tools and necessary accouterments were included, which was nice.

Cons:
 While the slid-on mounting brakes make installation easy,  there is a nut & bolt that hold the monitor to the stand so it won't fall off if you invert the monitor, but it feels a bit flimsy and I can't seem to get it tight enough for my liking (giggty).
 All the hinge points are controlled by screws tightened with the included Allen wrench, which mean if you're like me and you tend to change you viewing angle while working, you can't easily move the monitor to compensate.

This was easy to install and included simple clear directions.  The construction is solid, and I expect this to last me for years.

When considering the item I read a review that talked about the arms for the side displays drooping.  When I was half why through installation, I was convinces that this was going to be a problem, but by the time I had the third monitor installed, it wasn't an noteworthy issue.  Additionally, the instructions describe how to adjust the height of the center monitor, which is not completely obvious and I would not have noticed had I not reviewed the instructions.  My center monitor could probably use to be lowered a couple of millimeters, but I'm not going to bother for now.  I might adjusted it after it has settled over the next couple of months.

The one negative I encountered was that one of the plastic covers for an adjustment bolts had cracked during shipping.  I'm not certain I would have bothered contacting anyone for a replacement, but it turns out that a couple of spare where in the box.  Perhaps someone decided throwing in extras was cheaper than additional padding to the packing.

This stand was purchased forms as a gift and I really like it. assembly was easy and it holds my Asus 24" monitors without a problem. Once you have it assembled and the monitors attached it does get heavy but it is not unbearable. It is great for making space on a cramped desk or do as I have done and use it to push to monitors together for Battlefield gameplay or video editing.
