I purchased this keyboard tray about six months ago, and it was easy to install. Unfortunately, it will not stay in place! I have to attempt to tighten the main knob continuously, but it will not remain in place. The movement is extremely frustrating and makes it unusable.
The metal parts of this keyboard tray and the shelf are well made. The slide is also made well (design is like a rack sslide and uses ball bearings). The pieces I had trouble with were the threaded holes for the bolts that mounts to the slide. The holes were easily cross threaded and I had to drill 2 out and put nuts on the backs. The other problem was the use of threaded screws for pivoting up and down. This leaves a lot of play in the tray even when the knob is tight. I drilled those holes out to 1/4” and put a 1/4 shaft in their place. Much better. I have no issues with how far it is below the desk. It cleared my knees easily.
Easy to install and use, adjustments are very nice, great space saver. The ergonomics are lacking: small space for full-size keyboard and mouse, short vertical distance and no wrist padding. Works better with small keyboard and wrist rest.
Neck pain was the main reason I bought this item as my desk had under mount tray that pulled out but stayed very low. I was excited to try this and it does work great now that I can raise my keyboard and mouse up for my 90 degrees but after about 3-4 weeks I’m noticing the part that holds my keyboard/mouse is starting to lean, kinda tip to one side not sure if screws have gotten loose or what but wish this wasn’t the case cause its making it hard on my neck again and I don’t have packaging anymore and can’t return it if I can’t get this to fix.
