Firstly, I am a person who can not- should not build anything.The paper instructions frankly suck. They do not explain a thing- but if you're good at deciphering images they're good. (i figured it out you can too.) I couldn't use the disc which probably explained things better- like theres an up and downside on the hands that hold your screen.This also could have used a tool to install the springs. HOWEVER I used the Allen key and somehow didn't cause myself any severe injury.I got it built- took more hours than I am willing to publicly admit too- but i did it.I can not figure out the clamps, or at least haven't yet. I'll get that sorted soon I'm sure.It spins, the arms go up and down and I find it to be quite adjustable. So far It's great, I just gotta figure out how to make it hold my screens lol.
