Ergotron Standing Desk Converter (WorkFit-A)

Lightly used WorkFit-A, Dual Workstation with Suspended Keyboard. It's a sit-stand desk arm so you can convert your existing desk into a standing desk just by pulling up. I purchased this new from Ergotron for $700 + tax and shipping. Selling for $100 - I'm moving and won't be taking it with me. It's still selling brand new on the site: https://www.ergotron.com/en-us/products/product-details/24-392#?color=polished%20aluminum.
