Things to note of you have a desk made of MDF or substitute wood:- reinforce the plate/rail with a 1/2 inch thick wooden board- spread thin layer of gorilla glue on one side of the wood and press onto the underside of the table (in my case an IKEA countertop)- drill the guide holes into the wooden board- fasten the plate/rail with some stronger wooden screws that are long enough to penetrate both the board and table- finish assemblyI have more confidence that the tray won't fall on my thighs and feet now. I'll update this review in the future.Its heavy but looks sturdy and be aware of the length of the rail. You may need to cut the length to accommodate the depths of some tables. ### ⭐⭐⭐⭐⭐ Good product *by on Reviewed in the United States July 12, 2025* Been waiting to write a review after using it for several months. The only complaint I have is that I need to grease it because it squeaks a little bit from turning, but that is expected and normal. There are moving, functional components, which will always require preventative maintenance from the owner.When extended, you cannot put your full body weight on it without it flexing a little bit, but that is not why we bought it. It is extremely useful for our situation and we’re very pleased with it. ### ⭐⭐⭐⭐ Good range - Keyboard tray is uncomfortable *by on Reviewed in the United States 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. ## Frequently Bought Together - Mount-It!
