Top critical review
Not bad for the price, but beware monitors near the weight max.

I bought this after some back problems so that I could raise up my monitor while keeping my keyboard where it is. I still find that it is a bit low, but it's much better then the default stand.
The big note is that even though it says my monitor should be under the max weight. You really have to crank the hell of it to get it tight enough to stay in place. And not with the little wrench it comes with but with a proper closed-end wrench. And because it's just simple friction holding it in place, making any kind of tilt up-down adjustment loosens the bolt and will cause it to flop downwards.
Even knowing that I'd buy it again just because it's inexpensive and gets the job done. Just beware that if you have a heavy monitor, it's going to be a set once kind of thing, and you may occasionally have to tighten it again.
