### ⭐⭐⭐⭐⭐ Fantastic, sturdy, great texture. Ergonomic perfection
*by S***N on June 13, 2025*

Fantastic all around. Building it took 5 minutes. The build is sturdy, the clamps are plenty tight, and I have no fear resting my arms / upper body on it. Because it's a clamp on, there is no center mount to bump into my legs and my hands won't bump into anything at the sides of the tray. The sliding mechanism works perfectly.The material is great, it's textured in a way that is grainy but still comfortable. My mouse moves really fast on it but my keyboard doesn't slip. It feels similar to using an good quality glass eSports mousepad and I put my Artisan back in the drawer. The slanted lip means my hands are comfortable and the edge doesn't bother my wrists.My only wish is that they made a version that is 900x400mm (standard size large desk pad) with the same material, has a perfectly rounded lip, and maybe a tilt mechanism. That would be an instant-buy for me.Other than that, zero complaints at all. Gonna be using my desk like this for years to come. Transformed how I use my computer.Get the 34inch version. It's so much better to have all this space.

### ⭐⭐⭐⭐⭐ VERY Sturdy, largest tray available, HIGH QUALITY - But make sure you MEASURE!!!
*by K***O on August 29, 2020*

Update January 2022Tray is great but if you're like my wife who likes to rest her elbows on the tray... over time the (4) M4 screws that attach the sliding rails to the tray will strip. This will cause the whole tray to fall and can be quite dangerous. This happened at least 3 times until the screws were useless.I was on the verge of buying another tray when I decided to see if I can replace the screws. For less than a $1, I replaced the M4 screws with longer M4-0.7 x 8mm. You can get this at your local big box hardware store. I also recommend adding a dap of locktite on the screws as well to avoid them loosening on their own.This made the tray extremely sturdy without jamming up the slide. M4-0.7 x 10mm would be too long. So stick to the 8mm. I believe the original M4 were only 5mm.Highly recommend everyone to do this to make the tray more sturdy and safe. Wife is happy again! CHEERS!**********************WFH, my wife works at the dining table which isn't the best for ergonomics. After awhile her wrists/hands were hurting because the table, where her keyboard was, was too high. A keyboard tray would be the solution but since it's a dining table there were challenges to overcome and I got lucky with all the measurements.As a keyboard tray it's probably the best and largest one out there for an edge mounted configuration. I needed one to fit both a full 10-key size keyboard AND enough room for a mouse. This was the ONLY one that fit the need. The mounting hardware is very solid, heavy duty metal. For the parts that come in contact with the table, it comes with rubber pads for protection. It's sturdy enough to put some weight on, like if you wanted to rest your elbow on it.I'm going to provide some key specs that I couldn't find but is very important to know if it this will work for you:- The first is understanding the limit of how thick the table can be to use this. The max spec stated for this product is that it can support up to 1.75" thickness. I can safely say that it's an exact number. My dining table is exactly that thick. The mounting hardware will fit this thickness but it will be a bit tight, +/- 1/8" tolerance. So if your table is greater than 1.75" then this will not work for you as the mounting hardware will not fit.- Next is understanding the required depth from the edge of the table where you must have a flat surface underneath the table to clamp the bottom pressure plate to. The mounting hardware is attached via a clamp style mechanism. There is a metal plate at the bottom attached to a screw handle. You tighten this so it "clamps" to your table. This is important to note especially if your table has a recessed, beveled edge that curves underneath vs. a squared edge. Also sometimes, certain desk and tables have support hardware underneath that may interfere with the mounting point. My dining table had a recessed, beveled edge and it was questionable whether I'd have a solid flat surface to clamp to. PLEASE NOTE: FROM 1.5" in from the edge of the table, you must have a flat surface underneath the table to clamp on to. If 1.5" in from the edge of your table, the surface is curved, angled, or exceeds 1.75" in thickness, then you have no way to mount the hardware. 1.5" from the edge of the table is where the center of the screw plate.- Next is the amount of clearance you will have IF you have a 1.75" thick table. If you're pushing the max limit in table thickness, you are giving up clearance that may or may not allow you to retract the keyboard under the table when you're not using it. For me, I'm at the max thickness and as a result I only have 1.5" from the surface of the keyboard try to the bottom of my table. This means, my keyboard AND mouse cannot be taller than 1.5" in height. My wife uses a thin Logitech wireless keyboard that just meets this height but her MX Master 2 is too tall. As a result, while she has a keyboard tray she can use, she cannot retract it underneath the table. It was still worth using to be pain free. Since we're going to be in this WFH situation for the long haul, the need to tuck your keyboard away is trivial. I also should mention that if you have a ergo keyboard and it's important for you to store it underneath your table, it's highly this won't work for you. You need to have massive clearance for those keyboards.- Lastly, the one tip I have is some people have mentioned the keyboard seems to not stay in place if retracted all the way in or all the way out. I have the latter where the tray on the left side, for some reason, doesn't extend all the way out whereas the right side does. It turns out this is due to the mounting hardware on the side that has the issue being a bit rotated. All you need to do is rotate/twist the mounting hardware a bit to resolve the retraction/extension issue. Sometimes, what happens is my wife's chair will hit the tray and cause the mounting hardware to rotate a bit, which cause some warping or deflection of the keyboard tray tracks, which leads to the issue. The other problem could be that your flat surface is not leveled such that your mounting hardware are at different heights ever so slightly. Ultimately, the keyboard tray tracks need to be as leveled and parallel to each other as possible.I highly recommend if it works for your specifications.

### ⭐⭐⭐⭐ Solid Brand, but This Unit Had a Track Issue
*by F***E on March 30, 2025*

I have mixed feelings about this particular keyboard tray. While I’ve been a fan of Vivo products (I’ve owned a smaller Vivo tray for years with no problems), this one arrived with an issue right out of the box. The tray wouldn’t slide out fully, and I actually ended up hurting my arm from the limited keyboard access before realizing it wasn’t extending all the way. After giving it a strong pull, it finally slid out a few more inches—but it still catches at two points: nearly all the way in, and again almost fully extended.That said, the tray is very stable once in place and has a sleek, professional appearance. My previous Vivo tray still looks great after years of use, so I expect this one will hold up well aesthetically too.Vivo is still my go-to brand for keyboard trays, but if you purchase this model, be sure to check that the tray slides smoothly and extends to its full range right away. You may need to exchange it if the track is defective, as mine might have been.
