Okay - the positives - It was cheap and installation was relatively easy, or at least would have been if it'd been put together properly. The keyboard tray is wide enough for a full size keyboard and a mouse.
Now the negatives - All of the screws/bolts were very loose, one was barely on, and I had to tighten everything - a lot. In particular, there are two bolts that hold the arm attachment to the mount, these are extraordinarily difficult to get to, especially once installed, and they were very loose. This is also a design flaw - even with them perfectly tight they are directly in line (in theory so you can move the tray side to side (No one really does this though). As a consequence, this is what causes the tray to wobble something fierce once you start typing. I'm going to pull the whole thing down and drill out four holes in the corners to bolt the assembly tighter to the slide - that should solve the wobble, but its a step you shouldn't have to take. Lastly, the "rests" aren't really rests, but short little catches. They hold the keyboard in place, but even with a narrow keyboard you can't fit both a handrest and keyboard on the tray. You'll have to remove the existing rest and glue down a wider one if you want it to be really comfortable. The tray is also about 4-5mm to short on the narrow to fit a regular size mouse pad - you can trim one (which is what I did) and it will fit.
Summary - Budget tray, looks good, works so so, will require some modification/work on assembly install to get it up to snuff. If you can live with that (and I will) great, other buyers beware, you get what you pay for on this one.
This tray is a decent idea that is very poorly executed. If I had gotten around to unboxing it time to return it, it would be going back.
First off is the track issue. The track is narrow and centered right in the middle of the tray. Mounting it the way the manufacturer instructs means the front edge of the track is almost right up against the lip of your desk. Unless you have a low-profile keyboard or pull your tray all the way out while you work, your knuckles will bang on the track as you type. I have small hands, and even with the tray lowered as far as I can get it, my knuckles rap the track. You can *sort of* get around that by mounting it further back from the edge of your desk, if you have the desk depth to so do, but that really shouldn't be necessary.
On a similar note, their height adjustment claims are misleading. Unless you tilt the keyboard all the way down or all the way up, creating an incline and a recipe for carpal tunnel, you get nowhere near 6 inches of height adjustment. With the keyboard level, you maybe get 4.5 inches to play with. That's not enough to get your knuckles away from the track. I strong-armed it as far down as I could get it to go, and my knuckles are still hitting the track.
The mounting hardware is the big issue. For a $60 product, the screws shouldn't strip, and the metal shouldn't be prone to fatigue and drift. I may have to replace it after just a couple months of use, if I can't use the tips left in the other reviews to strong-arm it.
The 'gel wrist rest' is, well, awful. It's stiff, shaped like an ugly speed bump, and pushes into your wrist right where your carpal tunnel is. Luckily, I was able to rip it off without trouble, but it left behind a lot of adhesive to spend time removing.
If you don't remove it, by the way, you won't have the depth to accommodate your own wrist rest.
It has two things going for it. When the fittings are tight, it doesn't bounce around at all, which is a must for me. I also like that it lets you swivel the keyboard from side to side. I work in a tight space and often end up seated at an angle.
Overall, I don't recommend this product, at this price point, to anyone.
If you are like me and rest your wrist on little bit on the bottom of the keyboard frame or even if you are a heavy typer, the thing is going to move on you. I cannot get it to not move, after making sure everything is tight on it. I thought it would provide a better position to for my keyboard at my desk and in all accounts my wrists hurt more when I use it. I am unable to find a comfortable position with it, or when I do as soon as I begin to type the freaking thing moves on me. Not happy, but not sure what to do.
Not only is the screw very demanding (particularly for someone with hand problems that might drive them to buy such a device), and doesn't hold the keyboard in place under even the added weight of hands. You're constantly holding your wrists up, which causes different repetitive strains. Would not buy again.
As other reviewers note, it's fairly easy to assemble and mount but be sure to tighten all of the other nuts and bolts as you go. My big issue with this keyboard drawer was that you have to have it at a severe angle (bottom of your keyboard pointing at your toes) to get it to slide back under the desk. If you like the tray relatively flat, when you go to push it under the desk the keyboard hits some bumpers and you can't go any further. You're left with the tray angled down onto your lap...well actually no, you can't even get your chair close enough at that point as your knees are hitting the tray.
Pros - The product was well packed and neat. Its pretty easy to install. Cons - Product came with all sorts of black dust and scuff marks all over it. Its not study, and even after tightening the bolts i have to lift my arms so i don't put my full weight on the keyboard cause it'll will flop down. In the lowest position it is not ergonomically comfortable for my desk height. The little bars for the keyboard part on the top and bottom were not included in my package. If I hadn't waited to install this, I probably would've returned it and got a different product.
Nice and wide, slides in and out well. Nicely adjustable, but NOT SOLID ! It bounces up and down, just a little, as you type. I can just about tolerate it, for now (2 weeks) but It's wearing me down. I bet that people who can 'really' type, would go crazy. I'm pretty sure I'm eventually going to have to remove this, and replace it with something more stable.
The installation wasn’t bad at all. However, the tray would not really come up high enough for the ideal setting relative to my chair and monitor height. The main issue was that whenever I would rest my hands on the keyboard for a moment like you might if you were mid-thought, the tray would start to slowly drop. I didn’t want to tighten it too much per the instructions, but eventually the tray would just slide down all the time and became unusable.
This thing is built like a tank. It’s NOT easy to put together. Like at all. It shows that you need enough space to clear the cross bar but I wish it was clearer. It would help if it said what Mount-it desks it would be compatible with or without. I also wish they provided the brackets to install for use over the cross bar. Other sit/stand desks offer them.
