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)

This tray stays in place after tightening it slides in and out smoothly . This tray is not flimsy. The size is ample enough to hold a good size keyboard and mouse.

The good: this keyboard tray is the perfect size for my full-sized keyboard and mouse. It also comes with 2 adhesive mousepads to attach to the tray. The wrist rest is quite rigid, but overall comfortable. The clamps seem sturdy, and I am happy to have a tray that I can move side to side or remove as necessary.My one complaint: this should have been easy to install. And it would have been a lot easier if the tracks were placed properly. One of the tracks was placed too far in from the edge, causing the side of the tray to catch on the side of the clamp. I was unable to push the tray in all the way. This was remedied by unscrewing the track and using a drill to reinstall the track in the proper position. AFTER fixing this, the installation was easy. However, it really was annoying having to fix this issue myself. For around $70, I expected not to have to fix it straight out of the box. Aside from that issue, this keyboard tray is working well.

easy assembly. the only downfall was the keyboard didn’t really slide out all the way. so I wasn’t able to see the keyboard when typing. but overall quality is there, just not my preference on the keyboard not sliding all the way out!

A great keyboard tray and a perfect match for the "FLEXISPOT Essential Quick Install Standing Desk". Great shipping, easy to assemble, no hassle mounting, and smooth sliding action.Created a perfect ergonomic position when mounted with the Flexispot standing desk. Just to note the wrist cushion is firm and does extend the full length of the keyboard tray. Some folks like this only for the keyboard and not the mouse.Quick assembly and a solid mount, no wobble at all. Smooth sliding action that holds its position well. Includes two optional peel and stick mouse pads (Different shapes), very thin, and have a slightly textured, gritty feel to it.4 months in and no issues, would highly recommend!

Best keyboard tray I've had, maybe ever! Easy installation, just attach to runners and clamp to desk. Solid wood base. Very sturdy. The wrist rest is a little hard. Ok for typing, but I found it uncomfortable on my mouse hand. I got a little bean bag wrist rest for the mouse. Would definitely buy again. Tighten the screws every so often.

I bought the Flexispot desk, and used it for seated-only for a year before I moved out of my temporary office into a permanent space where I could stand. At that point, I realized I needed a keyboard tray. I ordered the keyboard tray, and immediately it was not very secure, in that if you tightened the screws all the way on the underside, it would click click click as you opened/closed it. After reading a review here that said to loosen the screws to avoid that, I did that (of course a screw eventually fell out and I lost it). Also, the clamps don't fully secure to the desk. The foam grips leave enough space to where the clamps often shift, and need to be readjusted/loosened and retightened on a near daily basis. With the pressure, the adhesive slides off the underside of the clamp, instead of keeping the clamp secure. After about a year of this, i reached out to Flexispot and asked for replacement foam pads, hoping that they've upgraded to better ones. Instead, they told me i'm past the warranty, so they will not send me these three cent replacement pads. Considering the fact that the clamps always swivel a bit, and the keyboard tray cannot slide out smoothly and straight, I cannot give this keyboard tray a good review. I wish i'd gone with another manufacturer. I assumed it'd be the best because it was made for the Flexispot desk, but definitely not. And considering it's about 3x the price of the other brands, it's not worth it. One star. Save your money, and get a different tray.

- I was disappointed to find Made in CHINA on the box. I did not know that before ordering...- The tray does NOT lock in place. For me that means it moves in and out if I happen to put slight pressure on the tray with my wrists while moving the mouse forward or back or barely bump it. This is a very bad option for me. I will either return it or drill holes in the slide to lock in place which defeats the purpose of a sliding tray...- I find the wrist support very annoying and not helpful at all. Cheap vinyl covered dense foam which makes my wrists sweat and it is hard to the touch. I see three screws that will hopefully remove this thing...- This tray is defined as "Large" but is not. My standard keyboard with mouse is very cramped on this thing. I'd widen 3-4".IN the end, this purchase was a mistake for me and unexpected as I like my standing desk from Flesispot, so far (just purchased a few weeks ago).Please go back to the drawing board and re-design or come up with options, especially with a lock in place feature while extended, a few inches wider and maybe a slightly recessed top so the keyboard won't escape if this wrist guard is removed.

LOVE this keyboard tray!!! Install was super easy onto my workspace counter! If you woke from home this is ideal!! It can basically turn any table or countertop surface into a computer desk which saves money and space!!! So genius!!! It also works perfectly with the Flexispot desks which I also have and LOVE! It’s very sturdy and provides great support for my wrists. Will be ordering another one very soon! Great quality products! Highly recommend this seller!
