VESA mounts are great. I use a pair of them. So much better adjustability, especially when your monitors come with the cheap pedestal stands that only allow tilt, not height or rotation.
However, the price is excessive. Recycling? Sorry, if I am dropping $295 on something like a monitor arm, I want to be able to use it on every monitor I own in the forseeable future. I don't care if I can recycle it.
I have a pair of VESA arms. Are they as adjustable as this one? Yup. Probably not nearly as easy (this looks like a smoothly moving assembly, whereas mine are tight and need to be pulled pretty good. However, I paid $45 for both. They don't look as nice, but they give me the same range of height, tilt, and rotation (in two axes) as far more expensive VESA arms.
