Review on Ergonomic Keyboard Tray With Retractable Drawer - Sliding Under Desk Platform [26” X 10”] For Mouse And Keyboard, Easy Assembly Without Tools Or Screws Needed (Black) By BigTron by Patrick Hamman

Easy to assemble and install. Works well with an optical mouse. Came with extra parts, two L-shape brackets and screws. Has enough room for a cup and mouse in addition to the keyboard.Unfortunately it did not fit my desk which is 1 3/4 inches thick. Removing the protective plastic end cap nuts allowed for installation. The downside is the bolts chewed up the paint. It is advertised to fit a desk 2 inches thick which it will without using the protective end cap nuts. If you need to use the protective end cap nuts the maximum desk thickness must be less then 1 3/4 inches.
