Ergotron Sit-Stand Desk Reviews

Works great with my 40 monitor

By James

The only thing I could criticize is that this arm is maybe a little bit better built than my monitor requires. Easy to install, easy to adjust, easy to use, solid as a rock. It's pretty much what I expected based on past experience, but it's good to see they're still cranking out good product.

Extra support for a heavy monitor.

I picked up a 2nd of this arm type to mount a Cintiq onto the same post that my original arm was mounted to. Is working great and looks good when you see it.
