Review: Difficult Instructions, but the product is perfect. - I bought it used. The instructions are difficult to understand. I had to professionally install, and I'm glad that I did. It turned out so nice. Perfect height for my elbow position/rest. I'm a short person. I love the long, wide body because I have a keyboard with a cushion and need more space.
Review: Perfect / Sturdy / quality Build - Perfect for my narrow tall standing desk. My desk is only 18 inches deep, so in lieu of installing it the Track the “normal way”, I installed it horizontally / sideways. This allows me to move the tray Left to Right instead of in and out, which is great for centering the tray within my workspace. The product came in perfect condition, easy to follow instructions, an is very well made - albeit a little bulky at the bottom. The single lever to adjust the unit vertically is super easy. This was definitely a great purchase

### ⭐⭐⭐⭐ Good range - Keyboard tray is uncomfortable
*by S***N on September 6, 2020*

Overall, the best under-desk mount that I've found for its range, not only in how close/far you can sit to the edge of the desk but also how high/low the tray can go as well as the angle you can set for the tray itself. I have a three-monitor setup with sit/stand mounts and adjust my workstation frequently as I work long days. I've tried a number of keyboard mounts but this is by far the most customizable. The keyboard tray is uncomfortable, however. PROS: *If I bring the keyboard tray to the front of the track it extends to a nice 18 inches from the edge of the desk. This is great during long zoom meetings when I want distance from the screen but may need to type a few notes here and there. I can also comfortably stand and type without "maxing out" the height. The mount has full 360 rotation making it easy to adjust the angle to align with my monitors when I move them. I can also adjust the angle of the tray so that the top of the keyboard is lower than the bottom, which helps ease pressure on the wrists. CONS: The keyboard tray/shelf is the cause of 4 instead of 5 stars. First, there is a bar that extends along the bottom edge of the tray. It is narrow and hard. The bar has a thin layer of padding, but not much. Since it's narrow (~1 inch) it cuts right into the wrist or palm and feels like I'm resting my hands on a ledge. Even with a wrist pad it cuts into the arm and has caused some numbness after a long day. The pad is glued onto the tray so it's possible to remove, but a pain to do so. Second, the keyboard tray has a slight springiness to it so that when you rest your wrists on the tray it lowers about .5 inches. Maybe a benefit to some? But a bit annoying for myself as I'm particular about the height of the tray. Since I work long hours it's important for me to have things "just right" otherwise it can cause a lot of physical pain. Third, if you like to have your feet flat on the ground or in a wide position, you will hit the lift mechanism with your kneecap. The lift is on the side of the tray, and extends ~1.5 inches in depth, and is ~3 inches wide. Similarly, if you like to work with the keyboard at "lap height" so that your arms naturally rest on your thighs, the length and springiness will make it so the tray feels like it's resting on your legs. Lastly, the tray is set up so that if you have both the keyboard and mouse on the tray, the keyboard is not centered to your body. This means that one arm or both arms are reaching further than need be to access either of these tools. This causes a lot of shoulder/neck pain in the long run, but if you center the keyboard then there is not much room for the mouse. Still the best mount I've used. Would recommend.
