Great keyboard and OUTSTANDING customer service
Summary: This is a great keyboard. It arrived on time and was well packaged. It's easy to assemble and clamp onto your desktop. The instructions are clear, the parts are solid -- real metal hardware and no cheap plastic parts. It's steady when you type; no wobbling even if you type fast. The tray is wide enough and deep enough to store my giant ergonomic keyboard and my mouse with a bit of room to spare. And it glides smoothly to store underneath your desktop. Or at least it does now ... which brings me to the reason I was prompted to write a review. VIVO's customer service is outstanding! Quite possibly the best company I've dealt with online or off. My excellent experience with VIVO: After carefully assembling the keyboard tray and attaching it to my desktop, the clamp on the right side seemed slightly off. No matter what I tried -- re-assembling that side, adjusting the tension -- the position of the clamp put the keyboard tray in a little bit of a bind on one side. The tray still worked technically, but was annoying. One side would slide in easily and the other lagged behind and had to be pushed a bit. I contacted the company through Amazon and got an immediate response. Based on the images I sent (which focused on the misaligned part of the clamp, but didn't show the entire clamp) they thought the issue was the slider rail. They offered me the option of returning the entire keyboard or receiving a replacement slider rail. I didn't want to be without the keyboard tray, since it was making a big difference in my hands/wrists/arms, so I asked for a replacement slider, which they promptly sent (and which also arrived quickly and was very well packaged). In the process of putting the new replacement rail on, I realized the issue was definitely not the rail, but was most definitely the clamp. One of the two pre-drilled holes in the clamp was about 1/8 inch off, meaning the keyboard was still sticking on the right side even with the new sliding mechanism. I reached out to the company again about the misaligned holes (this time with an image that showed the entire clamp). They promptly supplied a replacement clamp, which fixed the issue completely. The entire process was fast. The emails were prompt, courteous, and clear. And VIVO was willing to keep at it until the issue was fixed. Highly recommend this product and company based on this interaction.

Very satisfied. Solid item, beware of clearances!
Very solid, doesn't shimmy or wobble, smooth tray slider action. A quality item with solid steel construction. The only plastic parts were the backstop and the screw handles. The tray itself is composite wood. Large clamping surface gives good support. Back stop does not go all the way across, but that wasn't a detractor for me. It has two sizes: one for complete retraction under the desk and one that protrudes just a little. My desk has a horizontal bar supporting the table top that interfered with the clamps, but I put in a wooden block to provide an even surface underneath (see picture). If you don't feel like making this kind of modification to your desk, pay close attention to the measurements!! I bought this particular model because it was wide enough for both the keyboard and mouse.

Minor fixes made this perfect for my use.
This is a nice keyboard tray. There is a known issue of the tray walking away from you as you type. My fix was to purchase a Barrel Bolt Latch and mount it on each side to keep the tray from doing that. The extended pin prevents it from walking. Had this come with something like that, they'd have gotten five stars. The width accommodates my keyboard and my rollerball mouse, along with a wrist rest for each. My desk is a lesser cost up/down desk so I needed to take into consideration the measurement of the space allotment under the desk so it didn't interfere with the up/down drive pin. This works and I can move the keyboard at a whim, not locking me into a specific position at the desk. Value for the money I think is very fair. Drill accuracy was good, very easy to assemble. The ease of use is great. Put a lock mechanism into play on this and you have a great tray. I am very well pleased with this set-up. I don't need the tray to tip forward as the pad I have it on does this. I adjust the height of the desk for ccommodating my wrist/hand tilt. Ergonomic perfection? Nop[e. But it works for me.

VERY Sturdy, largest tray available, HIGH QUALITY - But make sure you MEASURE!!!
Update January 2022 Tray 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.

Sturdy, easy to install
Fits on my desk great. Tray moves easy and smooth. Easy to install. It’s not super heavy, so that is good for the desk. Durable for years of use.

excellent build quality
My VIVO MOUNT-KB05E keyboard works great. The build quality is excellent. I didn't want to drill into my new desk, so this clamp-on solution is perfect for me. The clamps are low-profile (flat) on the top of the desk, and far enough wide apart so that they wouldn't get in my way much even if they were taller. A minor cosmetic issue: The flat keyboard tray itself comes in two pieces. The two pieces are easy to connect together using a screwdriver on the included brackets and the result is solid, but there is a visible line between the pieces. Not a big deal, but I wish it was a single piece tray shipped in a longer box to eliminate the line and to be less work for customers when building. Before I purchased, the product information warned that a full 12 inches of clearance is required under the desk. That's true in the tray's regular configuration, but in the instructions that came with my tray, it explains there are additional screw holes for an "extended" configuration where the tray sticks out a little (about an inch and a half) in front of the desk when the tray is fully closed. I use the extended configuration which was a relief because I knew my Branch brand Office Desk only had 11 inches of clearance under there and I was worried about the tray not fitting. The product information also warns not to use this tray with a beveled-edge desk. My desk has about a half-inch bevel, which works fine with the clamp pads for the VIVO tray, so that's another issue I was worried about that turned out to be fine. Any more than half an inch of bevel looks like it would start to cause problems because the clamps need enough flat desk to press against. On my desk the clamp pads are just at the edge of the half inch bevel so I lucked out.

Ok for what it is but have some issues
Update 8/7/2023 - It's only been a few months of use but the right side of railing failed and does not come out all the way so when I take the tray out then it is crooked. This product is actually not that cheap and it's sad to see that it does not last a long time. I have a desk that I bought approximately 10 years ago at IKEA. I moved about 7 - 8 times during this time period and this desk stuck with me although it is high for my height. I just can't afford another desk. It's so high I'm practically typing and using a mouse with my shoulders at my ear level. I'm getting to a point in life that I can't sleep at night because of neck and shoulder pain after spending time at this desk whole day so I decided to buy this tray that goes in under the desk so my arms would be in more ergonomic position. And yes it works! I can rest my arms on the arm rest on my chairs and my shoulders and arms are in relaxed position. The package the item came with was very well padded and felt like a premium product. the tray itself came in 2-piece but has 2 metal brackets that holds it together. It feels thick and heavy and sturdy (that's what she said). The clamps it comes with also is beefy and does not wobble around. Now on a few issues. Although this product is wide so it holds both keyboard and a mouse, it is not deep enough. If I place my keyboard in the middle then my wrists hang out of the front edge of the product and has nowhere to rest my wrists. I have to push the keyboard allllll the way back to put my wrist onto the tray then I can't access the top of the keyboard. Also, because this is 2-piece I can feel the flex in the middle. Because my desk is too high I rest my elbow on the tray and put my hand on my face to ponder about life and I feel the flex in the middle. I'm worried about durability of this product but we will see. Lastly, the rail on both sides of the product so you can pull your tray in and out does not work smoothly. My right one is smoother than the left so if I try to pull the tray out from the left or right side then it gets stuck. I have to pull somewhat in the middle to pull the tray out smoothly. Overall, I think it's a good product. It was easy to assemble and I mean I have assembling ability of a 3 year old. It was pretty expensive for me, about equal to my monthly allowance, so I'm wary of the issues mentioned above.

An good improvement over the desk default tray
It a great improvement over my desk original tray and actually fits my kinesis advantage keyboard while still having plenty room for my mouse to be used on the tray. I can actually play games and work with the desktop space on my desk left for my pen display an now no long have to fight with a janky set up to do so every time I want to either work or play something. Easy to assemble and mount.

Solid keyboard tray
Needed this for my 49 key MIDI keyboard and it's the perfect fit, except for the height which I bought the height extender from the same brand for. So happy!

Solid product but needs design improvement (modifications required)
3.5 stars if I could. Quality bamboo surface is one solid piece, not laminated sections. Sliding mechanism is smooth and hardware includes extra screws which is thoughtful. However, the standard installation creates insufficient clearance between desk and tray. Had to install the rails backwards and upside down to get proper spacing, this modification voids the warranty but was necessary for practical use. The modification dramatically improved usability and comfort, making it actually functional for daily use. VIVO should redesign this with better clearance as standard. The current design seems like an oversight that forces users to either accept cramped spacing or modify the installation. Despite the design flaw, it works well once properly installed. Just be prepared to potentially modify it yourself if you need more clearance.
