This thing is great! It makes positioning up, down, left, right, back and forward super easy once it's installed. I'm using it with the Samsung CRG9, and a word of caution if you were using the stand the monitor came with you will need the unused metal bracket that came with the monitor to convert it to a standard Vesa Pattern.This arm is heavy, and seems really sturdy. The gas spring is awesome because it means you can position the monitor and it just stays in that position without having to tighten and loosen something every time.That being said it does take a lot of effort to torque the gas spring adjustment pin to provide enough resistance for a monitor as heavy as the CRG9. And it's really best to have two people for the entire set up process to make things easier.Lastly you may have to mount the arm pretty far to one side is the desk, otherwise your screen won't be centered on your desk.There is a YouTube video from this company on how to install this product which may be easier to follow than the paper instructions for some. Unfortunately the YouTube video is hard to find unless you search the name of the company and the model number of this item on YouTube. I do wish they just linked it somewhere on Amazon. Or posted the whole video on Amazon.But seriously, this product is really really good. At one third the cost of the alternative, the "Ergotron", I feel very happy with my choice!Update two and a half years later: Still functioning flawlessly! So happy with my purchase!
