Review on Made in USA Creator's Mouse Ledge - Black - Platform Laptop Chromebook Computer Extension - Slick Surface w/ Edge Guard - Portable Workstation by Greg Birchfield

I used it as an extension of the keyboard tray on my desk and it worked great. The extension has a clamp that is tightened with a screw and so far it seems to be pretty sturdy. It doesn't have much surface area, but I use a trackball so I don't care. It appears to be well made and comes with a small rubber edge to keep the mouse from slipping.
