There is nothing wrong with the product but for me I should have purchased 2 singles. You are limited on the adjustment centering high low etc. I'm keeping it but maybe should have spent a little more time on which one I should have bought.
I've dealt with arms similar to this that cost several times more and this particular set up is just as good. The only real difference is the cable management clips that are somewhat flimsier but for the price can't go wrong.
Easy setup. Quality product. First time I've seen the screws that go into the monitor have thick base so you can screw them in without need of a screwdriver. Huge for installing w/ one person!!!
It's works amazingly the plastic pieces that hold the cables in place are a tad bit loose but they are detachable which I like. It gives me full range of motion for my monitor so I can use it in any orientation I like.
