Installation was easy enough. Like, three options. There is a weighted base that you CAN leave freestanding (or so it says, I haven't tried it) but you have the option of screwing it through the table hub. The other two options use either an existing bushing or a self-drilled bushing. With dual monitor arms, it is IMPOSSIBLE to adjust the tension on these screws so that you can position the arms perfectly. And I mean, I grabbed a freaking POWER TOOL, found the right hex socket, set it up for maximum torque, and I smelled a burning motor and the bolt STILL wouldn't move. It's literally impossible, so you better hope you can get into the position you want with joints that actually move.
