FlexiSpot Large Keyboard Tray Under Desk Ergonomic 25 (30 Including Clamps) x 12 in C Clamp Mount Retractable Adjustable Mouse Computer Keyboard Platform Tray Slide-Out Keyboard Drawer Shelf (Black)

I've been using this for over a year. Not a single problem with it. I like the wrist rest. And it slides almost completely under the desk when I need it out of the way. It is sturdy, not wobbly. It is large enough for my keyboard and mouse with room to spare. I don't mind the look of the clamps on my desk, although someone might not like that, so look at the photos. Installation was easy. No complaints at all. I'm very happy with this keyboard tray.

The material quality is good, but it has sharp edges on both sides. Once it hit and scratch my knees

I do like that this saves the space that it does for the top of my desk, and that it slides under when you don’t need it. My biggest complaint are the tracks. The corners are super sharp right where they meet the edge of the tray. I’ve ripped holes in several pairs of pants just from crossing my legs. They also began to stick and it got more and more difficult to push the tray back underneath the desk over time. This happened on one side more than the other and it would end up sliding in at an angle and eventually the tray completely popped off one side and about a dozen ball bearings exploded out onto the floor. This was not because of excessive force either. So that was fun to try and fix. The worst was the day I pushed it under and didn’t realize the crazy sharp end on one side didn’t move under with the rest of the tray (probably because it had detached from the track multiple times before). When I stood up and started turning to walk away from the desk I got a pretty good slice to my right thigh that ended up getting snagged on it. Maybe I’m just clumsy? *shrug* I’m just saying, overall it is convenient and easy to install, but doesn’t hold up well over time and you may have to buy new pants and sustain some minor injuries.

The installation was very simple and I am able to fit my full size keyboard along side have enough space for my mouse. It is stable and I have enough space to type and move my mouse below the desk.

I have a FlexiSpot desk that I really love, so I wanted to go with the same company for the Keyboard Tray. I also wanted a tray that I didn't have to screw into the desktop and would be easy to remove. This item ticked those boxes. The box arrived rather damaged (but I don't fault the company for that...could have happened in transit). Upon opening, I found a large scratch/crack on the underside of the drawer (in picture). If it is a crack, it did not appear to be deep and did not impact the stability of the tray, so I was okay with that as well. (The position and length do not match the damage I saw on the box, so I don't think it happened becaue of that). Attaching the clamps was easy and I got it attached to my desk with no problem at all. The issue has to do with sliding the tray in and out. It isn't visible looking at the underside of the tray, but it appears that one of the runners is just slightly slanted in such a way that when trying to push the tray in under the desk, the tray hits the right side clamp and gets wedged against it so the tray does not easily go all the way in (in picture). The left side has a clear gap (also shown in a picture). When the tray is full extended, the gaps appear about the same. The size of the tray is great to hold a keyboard and a mouse and it is very stable to use, but it cannot be stored fully under the desk unless I want to be yanking it back out, which is disappointing. For the cost, I expected a bit better.
