Yep, it does the job well! The keyboard arm is sturdy, so no bending or flexing, the mouse tray works great. Even on the plain metal, the mouse works great, there's no reflection or anything, so no need for a rubber mouse pad on top of it. Both trays easily mount to the cockpit. Nothing else much to it, just a great addon that I'm glad I purchased with my RigMetal cockpit. It's definitely a required accessory for me.
