Uncaged Ergonomics KT2-b Under-Desk Adjustable Height & Angle Sit to Stand Up Keyboard Tray with negative tilt Best standing desk computer keyboard holder drawer

I found this better than the 3M or Mount It brand because the track was not too deep that it would extend beyond the depth of my desk as were the other 2 brands which stretched nearly 1/3 of their lengths beyond my desk depth and also KT2 is relatively lighter and more compact which is a good thing when it comes to installation. I also felt the KT2 customer service much more helpful when I called them to ask about how to install this on my desk which is a custom desk with a LIP extension in the front because of which the normal installation process of the track for this will not work. They promptly responded and gave me different alternatives such as buying a KT2 metal bridge . However since the depth of my custom desk Lip (2.5 inches) was more than the depth of their bridge (1.75 inches), they had their technical team send me alternatives such as building my own Wooden custom bridge for the depth I needed to clear the front lip extension of my desk which was about 2.5 inches . So based on their pictures they sent me, I did some measurements and brainstorming with the folks at HomeDepot, got the required Lumber and hardware and installed the bridge using liquid nails and 3" screws and then installed the KT2 Sit-n-stand Ergonomic key tray to the bridge using the screws that came with it as shown in one of the pictures I have attached. The process was timeconsuming mainly because I had to come up with a solution for the bridge since my Desk is a customized desk that is not ready for a keyboard tray without building the bridge. Only issue with the unit was since there is no padding at the end of the mousepad tray the Mouse can slide off in a slope configuration, so I created my own custom barrier for the mouse pad by taping 2 pencils as you can see to the mouse pad tray and now everything is cool. The keyboard does not slip unlike the mouse on a slope configuration because the tray comes with a couple of slip resistant rubber strips attached to it. Now that I have installed I am able to work peacefully without having to crouch over or bend my neck or stretch my neck towards the computer monitor to the point of pain as I was doing before installing this keyboard tray. I love both the sitting and standing positions of the keyboard tray as I can easily move it up and down and forward and backwards. Overall the KT2 sit n stand computer keyboard tray looks simple and slick and is a great product with good customer service that saved my day and I wish I had bought it few years earlier instead of straining my neck with some other unfriendly keyboard tray arrangement I had earlier. Since I just installed it a month ago, I just hope the KT2 lasts a long time for the effort I have put in to install and if that happens then I am a happy camper.

Hard to slide in & difficult to swivel easily. Not sturdy, mouse slides off due to angle of the lose mouse area-although it was tightened down as much as it would allow.. It hits the wall when slid in. Ergonomic keyboard slides off the back. The metal bars underneath hit & bruise my knees. I'm very disappointed and returning the item. Don't waste your time or money.

I bought this because it has an extremely unique value proposition - there's almost nothing on the market that offers both negative tilt (I have wrist issues) and easy conversion between sit/stand, especially not at this price point. And for being in rare market space, I'm very happy with it after a few days. With that in mind, I give it 4 stars for being an innovative product that truly addresses ergonomic needs. However, there are lots of minor opportunities that could make this a truly phenomenal product. PROs: - delivers on relatively easy sit/stand conversion - offers separately adjustable mouse platform - negative tilt in a standing tray, hooray! - definitely feels sturdy CONs - adjusting from sit to stand requires multiple adjustments. If you’re not careful, you’ll drop your mouse and keyboard on the ground. - the “slide out” tray is more “drag out”. Future iterations should have proper drawer slides with smooth bearings etc. - The keyboard tray is a bit small for me, but I admit I have excessive keyboard needs; I’d like to see it both deeper and wider. - To better support tilting options (especially negative tilt), there should be barriers that prevent the keyboard and mouse from sliding off the front and back of the trays. The grips are decent, but the mousepad requires glue to keep it in place, and I’m still nervous my keyboard will slide off the trays during high degrees of tilting. Barriers should be at least an inch high to accommodate tenting keyboards - some of the reviews have said it's challenging to assemble. I didn't find the instructions difficult to follow, but it does seem like there's something off with the manufacturing process. One of the holes on the platform didn't line up with the metal piece on the mouse attachment, which resulted in a crooked screw that almost immediately got stripped. And it was damn near impossible to get out. 90 minutes of blood and sweat later, I was finally able to complete the assembly. Long story short, I'd encourage the manufacturer to use higher quality screws and exercise more care in making sure it puts together easily. Overall, I’d encourage anyone to try this product if they have wrist pain and want a convertible standing desk option. But expect to put up with a bit of hassle. And if the manufacturer sees this review: THANK YOU for innovating. I hope you keep iterating on this product to make it truly excellent.

This product is 100% fit for my purpose. I wanted to be able to work both sitting and standing, but not be reliant on costly electrical mechanisms to adjust the height of my desktop. The alternative was to have an adjustable height keyboard tray and monitor stand. I needed a product with an 18-inch verticle range to match the distance I move from my ergonomically ideal sit to ideal stand positions. This was the only stand that provided this range. My stand came with all the required hardware including allen keys and was adequately packaged. I agree that the mounting of the tray to the central lever is quite fidly, and I also had to tighten the height adjustment cable. The keyboard tray does wobble as a consequence of the single central mount, but this is not excessive, and probably helps reduce RSI! The stand attaches firmly onto my solid wood desktop. I would like to see the mouse pad set on the same level as the keyboard tray and for the angle adjustment to be by a hand-tightened knob instead of an allen bolt. This would be a better ergonomic position for me, and allow for quicker adjustment. I alternate between left and right mouse so would like two mouse-to-tray mounting assemblies to be offered as an option. Finally, it would be useful if the tray angle adjustment lever was longer so it could be operated from the front of the tray at the same time as the height is adjusted. It is awkward adjusting this from underneath. Thank you Uncaged Ergonomics for innovating in this space.

I think I will enjoy this product. I certainly hope I do, taking into account what a raging pain in the (expletive deleted) it was to put it together. The "instructions" have a picture of the included parts... which is incorrect. Steps 3 and 5 were already done, so I had to undo step 5 so that I could get A and B apart and start at step 1. The steps are pretty straightforward, until you get to 6, which tells you to use the screws and nuts that come in the little baggy. Unfortunately, there are two little baggies of screws and nuts, which are not labeled and look ALMOST identical. You get to try them each and find which one fits into the holes. Once you have successfully deduced which set to use, you just pop the screws in and then put the washers and nuts on the other side. (I'm assuming this is what the washers were for, as they are not in the parts list or instructions.) Putting the washers and nuts on is really easy... IF you happen to have three hands, some tools, and eight inch long quadruple-jointed fingers. It's incredibly difficult to reach in where you're supposed to, and it took a really long time and a lot of swearing. Finally, after all that, it's on to stage 7. Step 7 "The mouse pad attaches to the right or left side of the keyboard tray". At this point you use your magical powers to contact the spirit of the engineer who died in your house so that he can tell you HOW the mouse pad attaches to the keyboard tray, 'cause the instructions don't bother. Being a semi-intelligent person with part of a college degree, I theorized that this was the reason I had two unlabeled baggies of screws and such, instead of just one. What do you know? Those screws were much easier to deal with, though they still required strange wrench contortions and curse words. Steps 8, 9, and 10 tell you how to adjust the new hardware you have installed. Okay, pretty good. The big stick-on rubber piece might not actually belong here, since it's also not in the instructions... However, it's the same size as the mouse pad, so that's where I stuck it. After the long, drawn-out, incredibly joyful experience of putting this thing together, I was too... tired (and stressed out) to deal with actually trying to use the thing. It had better kick ass.

The Tray that mounts to the bottom of your desk is sturdy. The arm which slides out is as sturdy as can be expected for something that rotates, I have no problems with that; however, the platform the keyboard mounts to is like a think cutting board (have you seen those warp before?) and the mouse platform connects directly to the keyboard platform which makes that the least sturdy of all. I bought two of these, I am planning on going to the local hardware store and buying a thick piece of wood (the length and depth of the keyboard and mouse platform) and some longer bolts. I will lose the adjustability of the mouse platform but I will gain a solid platform. I just did not like having to spend extra money to make this usable for me.

Pro's: 1) The alternate angled installation I used (see pictures) allows it to tuck away under a small tabletop. 2) Lots of different ways to set up a desk & keyboard tray. 3) Frame is sturdy, plastic tray is a bit brittle like Bakelight 4) Keyboard & mouse tray combined make for a full working deck. 5) Room for wrist pads on both trays. 6) Mouse tray can install left or right, & at two different elevations. Con's: 5) No retaining rails or ridges on either tray, but adjusting the tray requires putting the mouse aside on the table top. 6) HEAVY: It's difficult to retract inward or outward, there's a fair amount of drag due to its weight telescoped out past the desk edge. It's necessary to lift the arm up sufficient to ease the binding in its track. Although I don't doubt that some bar soap rubbed into the track might help I'd suggest either using lighter metals where feasible, and/or set rollers inside the arm track. Here's an alternate installation under a small "Origami" tabletop, still allowing complete fold away

This keyboard tray is HORRIBLE. I have had it for almost 4 months now. The mouse tray cannot be tightened to the degree needed to keep it from tilting and it squeaks constantly. The keyboard tray is only supported in the center so it tips some from side to side so it is not ergonomically sound. The mounting to the desk is fine, but the tray it self is SEVERELY lacking. Additionally, you can't really use the tilt that I bought it for because the surface is such that even a mouse pad slides off when it's barely adjusted. I have had to put headbands and scrunchies on the edges of both the keyboard tray and to keep them from sliding off. If you didn't have carpal tunnel before using it, you will now.
