EUREKA ERGONOMICHeight 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.

This tray is fantastic. I would buy it again in a heartbeat. I just don't think that i'll get to that point. I'll go into a bit more detail.Comfort: This tray is very comfortable. It is very easy to adjust. Adjusting this tray is all done via one knob, which is located under the tray. This knob is the only problem that i have with this tray. This knob allows for the entire tray to be adjusted to fit your needs, which is incredibly simple to use. The problem is not with the ease of use, it's with the location. When i slide this tray over my lap and then i slide my body under the tray, this knob resides exactly where my knee wants to be. Disregarding this unfortunate placement, this tray is extremely comfortable, and even offers some limited negative tilt (which i prefer)! At first, i was concerned by the method that the tray slides back and forth, which is just some sliding plastic on metal rails. After using it for a while, it occurred to me that the design was simple on purpose. It is not easy to slide, which keeps the tray in place without requiring a locking mechanism. This allows me to slide the tray in and out without adjusting any knob, but also keeps the tray in place unless i want to move the tray!Sturdiness: This tray is very sturdy. I am the kind of person that leans on the keyboard and slams on the keys (from learning to type on a typewriter), and this tray doesn't even budge when i type on it. It feels like i'm typing on a desk! It allows for multiple movements, which do not affect the sturdiness of the tray. This tray is incredibly sturdy. I speak about how i mounted it in the next paragraph.Easy To Install: This entire tray was not difficult to install. The tray arm assembly can come out of the rail itself, which makes installing the rail underneath very simple. I installed this using the standoffs, as i have a very complicated situation on the underside of my desk. There are actually more orientations under the desk than are advertised, as there are extra holes in the rail! this made it so the very limited space that i had under my desk could be effectively utilized. I would recommend pre-drilling some pilot holes in your desk to ensure that assembly is easier, but other than that this was a breeze.

This sucker is BIG, so make sure you measure your desk, especially if you have shelves or drawers on one side.It has ample room for my die-hard Model M keyboard. The height and tilt adjustment is awesome -- I hurt my left wrist, and tilting the front of the keyboard up helped tremendously.It is sturdy and steady and does not budge while typing on it, and i lean my wrists on it while doing so.I don't have room to leave the keyboard on it when it's retracted, mainly because my CPU tower is also under the desk and it is TALL. (no, i'm NOT compensating for something!)It took me a good while to install, with my new Bestier desk, I had to use a nail to start the screw holes, as well as a Dremel to start the hole. I don't mind, that means the wood is tough enough to hold this. Had no problem with the metal frame of my desk.The diagram shows to screw the first bracket in front of the metal frame, but there wasn't room for me to do that. No matter, it fits behind the frame just fine.The only downside is, it does not 'glide' smoothly in and out. As recommended elsewhere, I hit the rails with some WD-40, and that did seem to help. I guess at least it doesn't roll away when you lean on it.Strange bonus: since I got this keyboard tray, my cat no longer tries to use my keyboard as a pillow while she's sitting on my lap as I type. ;D

First off, this is a great item for someone who doesn't want to have their mouse and keyboard on top of their desk and have a little extra freedom with movement. So lets get down to the pros and consPROS: - Nice sturdy tray with multiple movement paths. ( tray movement side to side up and down )- Full mouse pad for tray and the ability to remove the wrist rest- Easy install ( pay attention to YOUR setup since there can be 4 different ways to hang it )- Comes almost fully assembled. (It's about 6 pieces )- Easy to follow instructions- Comes with a screwdriver for installation- Nice self tapping screws. MAKE SURE they won't bust through your desk!- Screws are all phillips head so you can use your own tools if you don't want to use the includedscrewdriverCONS: - A little tough to pull in and out. I would recommend a little WD40 on the track to help with the tray being pulled in and out. It can be a little tough and may shake your desk.- The wheel to loosen the tray is LARGE. This is a bit tedious for someone like me since I'm taller so it may take some getting used to. I keep bumping my knee on it.- Instructions may be easy to follow but the print is SMALL. This one is just my opinion.In a nutshell, this is a very nice item and is sturdy and beefy. The sliding mechanism and arm are heavy so it shows that it is made with quality. This isn't some simple store bought item. It doesn't wobble and works like a champ. It can hide completely under your desk so you're not stuck sitting farther away from your desk. Just remember, this does hang down from under your desk so you may need to adjust your chair.
