only thing is you'll have to tighten the nut pretty good for it to stay when i rest my hands on it. other wise easy to install and works great.

Easy to install. Pretty good, but sliding not really smooth. Overall, it's a good value.

vraiment bien mais les vis son vraiment cheap j'ai utilisé les mienne , sinon une fois installé, cela semble de bonne qualité mais un peut sur a l'ajustement

Workable solution and good deal

Jaime beaucoup ce support à clavier.

Similar to other reviewers: for the price, this is a sturdy keyboard tray that is highly adjustable. I had no issues installing it on the massive piece of heavy driftwood I call a desk. The structural components are metal, and the overall construction feels high quality and sturdy while allowing precise vertical/rotational adjustment. However, the keyboard holder insert isn't quite sized right to prevent horizontal give, which means that pulling the keyboard in/out is not linear nor smooth, and there is an annoying horizontal rotation that happens if you press the keyboard horizontally that I haven't been able to figure out how to prevent. While the rotational adjustment is sturdy, the tightening nut is not sufficiently strong to prevent slight pressure on the keyboard tray from inducing some vertical motion (meaning: every time you rest your hands on the tray to use the keyboard/mouse, the tray moves down almost a centimeter, which is very noticable and irritating). With some creativity, the two problems I've listed can possibly be fixed (though I haven't proven to possess the requisite creativity yet), so this isn't a perfect tray, but for the price it's doing the job and most of the parts are high quality.
