Sturdy, but a little hard to assemble
Your review: The keyboard tray makes using the wire racks to house a farm of workstations look neat and clean. However, review the instructions prior to assembly and pre-fit the brackets, also two people really speed things up since they need to be held in place and tightened at the same time.
Once in place it works pretty well, it pulls out relatively smoothly though you may have to tweak the bracket location to get the movement really smooth.
