Gets the job done
What you see is what you get. :-) I was concerned about the desk clamps getting in the way of my work space but they are so wide apart it isn't a problem. Obviously the height is not adjustable, but if you have an adjustable desk you can get around that. I personally like that there is room for the mouse pad because I don't like having my keyboard and mouse on different...

Not great for thicker desks. Bubbling laminate
I reviewed this drawer not long after receiving it in Jan 2024 but am updating after having it for around 4 months.
My initial complaint was that although the clamps allow for desks up to 2.5" thick, the space between the bottom of a thick desk and top of the platform is so minimal you have to use very low profile keyboard or mouse if you want to close the drawer. I ha...

excellent
I bought this to replace a very old shelf that kept needing adjustment. This slides so smoothly and has room for the mouse too. I can rest my arm on the arm of my chair so my shoulder isn't sore. I don't know how it was to install because someone did it when I wasn't home.

Great addition to a stationary desk
Tray was super easy to put together and install. Tray needs to be installed on a straight desk (no curves as it won't sit flush like it needs to be and the tray won't go in all the way if it isn't level). Works perfectly for what I need it to be. Helps with ergonomics.

Disappointing For Desks Near 2.5"
I searched for a long time for a keyboards tray with clamps for a 2 !/4 inch thick desk so I was happy to find this one. However, once I had it put together I realized actually using it with a desk that thick was a disappointing outcome. Due to the overall design of the hardware, using it with a desk anywhere near 2.5" leaves so little room between the bottom of the des...

It was great until it wasn't
I really loved this under desk keyboard mount until one day I went to push it in under my desk and it wouldn't close all the way. I took it off my desk to inspect it and found a screw missing, but that didn't explain why the track would close on one side. Really sad since I only had it for about 1.5 years and now will have to buy a replacement.

Looking forward to using it
This tray will help me a lot since it will be under the desktop. I am waiting for a friend to assemble it for me.

Solid product
Very pleased with the way it frees up room on my desk. The build quality was very good and it feels very solid and stable. I use a vertical ergonomic mouse, and there isn't enough clearance under the desk for the mouse and a thick mouse pad, but I find that the mouse works fine on the keyboard table itself.

Solid and easy Install
Built to last this was an easy assemble and install in under 15 minutes. I'll probably purchase a few more of these for fellow employees that are using flimsy trays made by some of the more well-known brands.

Sufficient
Not exactly completely adjustable (can't move up or down) and not very detailed assembly instructions. However tray is good quality.

Good product
This was not hard to mount; no drills no crawling around on the floor. It works fine. It has not height or tilt adjustment but has plenty of space.

Epic fail
What they don't tell you is that you need 33" clear inches or your drawers won't open because they run into the hardware. Directions for assembly are not good and takes a long time to figure them out and I am mechanical. I would never recommend this product.

Simple and best solution
I was able to install this tray myself and there is plenty of space for my keyboard and mouse. This is the third one I've tried at my new desk - the other ones were articulating keyboard trays and I had to get someone to install them and they were so small that my keyboard and mouse barely fit.

It’s ok
The tray no longer slides all the way in. I have had it for a short amount of time.

I can't use it for two reasons 1 the holes on the sliding bars don't match up on the tray 2 the sliding bars are mounded up side down .

Exactly what we were looking for
This was very easy to put together and mount to the desk. Since this office is just temporary the clamp feature makes it easy to remove and reinstall in my permanent office without damaging any furniture.
