Uncaged ErgonomicsKT2-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.

This keyboard 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.

Maybe I am just picky or spoiled, but back in another life I sold office products when adjustable monitor stands/mounts & keyboard trays 1st came into being and carpal tunnel was the hot topic and I sold 1000's of both. I had a HumanScale KB Tray, but it was 20+ years old and needed to be replaced. So when I saw this KT2 sit/stand adjustment with separate adjustable mouse pad and it was in the mid-level price range, I was interested, on paper it seemed to fill my needs.The mechanism itself seems very sturdy & stable and it may not show so well in the attached pic it is 100% level before the tray was attached. Well that all seemed to change quickly after the tray & mouse tray was attached. As you can see where I pointed it out it goes from a 1" space on the left to 3" on the right of the mouse pad. I have removed both trays, rechecked the level which passed the bubble test and then reattached the trays and the lean to the right was still there.Other issues are the height adjustment under the keyboard tray is a knee buster if you are not careful and paying attention. The tilt adjustment for the keyboard tray with a pull away lever adjustment is not a good design, should just be a knob as the lever makes that adjustment cumbersome. The mouse tray is nice, knob adjustment for both left/right & front/back adjustments. The posititivity ends there. if you want a positive tilt (edge closest to you) get ready to catch your mouse as it slides right off. The same goes for a negative tilt, you will have to chase your mouse under the desk there are NO provided stops provided.Bottom line is for the price, steer clear. Since I have just installed this today (5/18/2023) I will give it a couple of days, maybe it just has to settle in, but I will not be holding my breath.

Verdict: great customer service. KT2 is worth the $100. If I were to do this again, I'd look for something with more vertical stability. The bouncing while I type is really annoying. The use of plastic bearings was probably done for cost, but it makes repositioning the tray difficult.Assembly: be prepared to drill, measure, and experiment with the optimal location for mounting the KT2 to your desk. It took me about 2 hours to mount the KT2 on my Ikea Idasen sit-stand desk. The KT Bridge wasn't tall enough to clear the Idasen's crossbar, so I needed to get four plastic spacers of the appropriate height, an item far more challenging to find at my local hardware store than expected.Use: my biggest complaint is that the KT2 bounces up and down quite a bit when i type. Putting my hand on the mouse pad also causes it to tilt. A minor complaint is that it's difficult to push the tray in/out since the arm and rail use plastic bearings.Customer service: the first KT2 I received noticeably tilted to one side. I contacted customer service via email who promptly shipped me a replacement KT2 after sending them photos demonstrating the tilt. Unchained Ergonomics is one of the few companies who manages to get email customer support right.
