EUREKA ERGONOMIC Height Adjustable Mouse & Keyboard Tray Under Desk, 28x10'' Large Slide Out Swivel Tilt Computer Keyboard Drawer with Mouse Pad for Gaming Home Office Desk, Dual Mount

I used this for a custom built desk, and it fit perfectly. The keyboard tray seems to be holding weight perfectly fine even after six months of almost daily use. The keyboard mat is very nice and slippery, great for gaming on. The shape of the mounting bracket is perfect for going around support structures under the desk, and is actually adjustable which is very convenient.

I ordered this for my work office desk. It was packaged very well, and all the pieces were labeled well making everything easy to identify. It even came with real tools to assemble it and the instructions were easy to follow. It was very easy to install, and it is very sturdy (holds in place once I've set it where I like). I've read some people state it's hard to pull out when pushed in under the desk, but if you lift it up slightly as you are pulling it out, it glides easily.I love that it is highly adjustable (tilts, turns, and swivels). The only thing that caught me off guard a little was that it is very wide. I didn't pay a lot of attention to the measurements when ordering as I was focused mostly on the features, but it just barely fits in the space I have for it with only an inch or so on either side remaining (the desk has built-in file cabinets/drawers on both sides). That being said, there is a lot of room to move the keyboard around and lots of space to hold your mouse - and a phone - and even more accessories. If you have a desk that is small, I'd suggest double-checking the measurements.

Works well for electronic standing desks - it fits over the bars nicely and provides more cable routing support under the desk if needed.A little wobbly left to right but not a huge deal. Its the spacing of the slide device not the tray itself etc. Everything feels solid and is pretty well machined.My biggest gripe with all of these types of under desk keyboard trays is that they never come out far enough. For tall people who like to put their legs up and not have their face right in the screen, they need to come further out.The palm rest for me was extremely hard and caused a lot of pain. I was so thankful it wasn't glued on and could be unscrewed from the bottom. Plus it provided a bad angle for my keyboard, mouse, and chair. Now that leaves three holes in the tray but whateves. It would have also been nice to have had a full tray mouse pad incase you wanted to take the wrist pad off. I've bought a couple full size that I'm going to cut down to size and use double sided tape probably.I am actually considering making a new keyboard tray that is longer since that's probably the easiest modification to get some extension from it.A manufacturer fix could be: they could make the slide metal longer and have a couple stop locks that can be repositioned to allow the tray to slide out longer for people of different heights that need to be a bit further away.Another thing for standing and typing that might be good is an attachable tray wall on the top for negative incline typing.Overall, I am fairly impressed with this keyboard tray and the flexibility of it. I hope they address my concerns for the next version or separate version released.Lastly the adjustment knob underneath, its not the greatest and does hit the knees sometimes and you need to reposition, but not terrible compared to others I've used. I've only seen one other super expensive brand that had a longer metal arm and small adjustment knob on top, but that one itself had tons of flaws. Something like that probably wouldnt work with this design.Another thing to look into if you need more flexibility and ergonomics like me, is using a wireless keyboard and mouse and trays that attach to your chair instead of the desk.

I read some of the reviews and was expecting less from this keyboard shelf. I was pleasantly surprised at the quality and size. It fits my full size keyboard just fine and has a lot of space left over on the side for my mouse. I play a lot of games on my PC and it feels great during long play times. Mounting it was not difficult and all the hardware needed was included. It looks like it was part of the original desk.

UPDATE: I'm still more or less satisfied with the tray, but in a few months some moving parts became a bit lose and started making rattling noise while I'm typing. Just an annoyance but may be a deal breaker for some people.The tray is very good - big enough for my Logitech K860 plus mouse, sturdy and adjustable. But there are a few minor problems.1. The in/out sliding mechanism does not have any bearings, so it may take some force to do it. I'm still getting used to slightly lifting the tray to make the sliding easier.2. The adjustment knob is not used too much, but it's rather big and located so that I often bump it with my knee. I'd prefer the knob and the frame to sit a bit higher or deeper under the desk.3. The wrist rest did not work for my and I had to remove it. It's not a bit deal, but now the tray has three bolt holes and the pad cutout right in front of me. This could be easily fixed by including a low profile pad of the same shape as the wrist rest.
