Top critical review
Easiest of all to setup. Not a lot of height. Locks in place well, but not independent. Shakes like an earthquake.

First of all, this is probably the easiest monitor stand you'll ever set up. To begin with, of course, the desk mounting system guarantees a lot less actual work (no drilling or anything.) Definitely good for someone who needs a stand and doesn't want to deal with a lot of tools. You pretty much just put the right piece on and twist to tighten it in place. (It can go through a desk grommet or just tighten on the edge. I honestly don't see the value in the extra work of using a grommet except if the desk is actually screwed into the wall or something silly like that, but it's there if you want it. Just a lot more work to do it that way without any gain I can see.)
One complaint I have about what I replaced this with is that my replacement does not lock well. That's one thing I definitely miss about this one. This one locks exceptionally well. Once you get the screen how you want it, you just tighten the bolts a fair bit and it's not going anywhere. Even if you bump it the screen will stay where you put it. Even the tilting mechanism can be tightened sufficiently that it never moves until you want it to. Since it requires that you use hex keys to adjust and you might not need to adjust again for potentially years it's also really cool that it stores the tools that came with it on the bar itself via a snapon plastic piece. (Although the hex keys that come with it are steel colored so stand out a fair bit. Kind of oversight, but it's hard to really see them anyway.)
There are only three complaints. First, the two sides are connected together in one piece on the bar and this is the only height adjustment available. Thus if you have two monitors that are not the exact same model there is a decent chance they will not actually line up. The locking screw on the rotation part of the actual mount itself can be used to slightly adjust the height, but only by maybe three or four centimeters. So chances are if you don't have matching monitors they won't be lined up with this no matter what. Still, in most cases it's not that bad. If you're going for something of a more seamless look for super-wide screen gaming or something you don't want this anyway (especially since you really want three monitors for that.)
Second, the height doesn't go very far up. I found it to be too low even on the maximum with my desk. Perhaps my desk is lower than most or something, but I think it's a fairly standard size really. Oh, and I am not a tall person.
But unfortunately my last complaint is a big one and ultimately the reason I replaced this when it otherwise worked fine. And, unfortunately, this is a simple problem of physics (and should have been obvious to me.) You see, it shakes like mad. Unfortunately, the problem is fundamental to the nature of this type of mount and not really fixable. You see, it comes down to the fact that you have one or two monitors attached to a single relatively thin bar clamped to the desk. This means it will have some give and the screen will shake any time the desk shakes and, unfortunately, it takes very little actual shaking on the desk to make the screen shake. Unfortunately, I don't mean bumping into the desk or anything like that. Just typing at a decent pace (not even super fast, just a decent pace, nor do I mean hitting the keys hard or even using a mechanical keyboard with tough switches or anything) causes the screen to shake a lot. And it shakes so much that it leads to eye strain and fatigue over time of actually using your computer. Definitely not a plus. This is not in any way the fault of the manufacturers but just simply the nature of the design. Unfortunately, I can't recommend this except as just a quick-fix for someone who can't install a more proper wall mount than anything else.
