This product has truly been a ergonomic lifesaver for me. I bought this because I have two remote jobs at the moment, meaning I am on my computer and desk for most of the day. Because I have so many monitors, keyboards and laptops that I am working with, my desk gets cluttered very easily. I took a chance on this product and it paid off tremendously.Pros:1.) Easy to install- it took me about 30 mins to install this on my desk and the instructions are very clear.2.) Durable- I have been using this since August 22nd of this year and it has shown no signs of wear and tear so far. If I am eating food I can put multiple plates on it as well without issue, so it functions as a makeshift second table as well.Cons: None so farPoints to consider:1.) Make sure your desk is both thick and long enough to accomodate this item. I have seen several other reviews here mentioning the same thing and so before I bought mine, I measured the length and width of my table to make it easy.I received the item and it was well packaged. I like that one of the clamps has the logo of the company. It's not tacky at all. It is sturdy enough for me. Unless you plan on resting your elbows and leaning on it, probably not that sturdy, but for normal usage such as typing and moving your mouse around it's perfect. It was easy to install. The sliding mechanism was already attached to the tray and all I had to do was screw in the clamps which was pretty straightforward. One of the videos showed an incorrect placement of where the screw should be, you can't miss it. There are 2 perfect holes that fit the screws it came with to attach the clamps on the tray. Also, the instructions are on the back of the box, which I think was pretty cool.I have an ergo key board and mouse on the keyboard tray. It is rock solid and doesn't bounce as I type like many other keyboard trays do. The only downside is you can't adjust the elevation - the distance between the keyboard tray and the bottom of the desk - and my ergo mouse doesn't fit the opening between the two. Thus, I have to remove the mouse and place it on top of my desk before I push the keyboard tray in.Once I got it set up, I love it. I expected the instructions to be a small pamphlet in the box. I struggled to get the handles installed properly and had to switch them because i had it backwards. I didn't use any instructions so that's my fault. I should have turned the box over. but now that its installed, I love it.Just what I needed. Work station is more comfortable..used the Styrofoam that it came with (in box, for packaging) to put in between the clamps for the desk I had. Work out perfectly.. Now fits securely..I am giving the product 5 stars because the product worked great. Unfortunately I kept banging my knee on the item and there was no way to lower my chair or raise my desk.After a couple years of battling with the original sliding tray on my desk, its runners finally gave out. I detached what was left and decided to take a shot on this replacement tray. The item arrived much more quickly than the shipper indicated (which was a huge bonus!) and it was easy to set-up. The tray requires four screws to attach the clamps to the tray, and they screwed into the provided holes with no issue. That's it, there was nothing else to do. It was ready to install!If you appear to be missing the screws, I suggest checking the plastic wraps the other pieces of the product come in: with mine, the packet with the screws was taped to the covering for the large keyboard bag, and I almost threw them out as it went unnoticed at first. The screws are very small and light, so if you think they're missing, I would carefully check over the keyboard bag.This isn't relevant to everyone: I have a glass desktop with a slight convex curve and a floating support cross-bar underneath the desktop, about 1-inch back from the edge. The clamps and pads attached to my desk without problem. The bottom flange of the clamp did not run into the bar; the bolts that fasten the clamp pads to the underside of the desk did run up against the support bar to a slight degree -- resting directly against it -- but not enough to impact the tray's stability or ease of installation in any manner. (If your support bar runs directly up against the desktop and is also less than 2-inches back from the edge, this product will likely not work for you.)Be aware: if your desk's design is like mine, with the bar and the height of the clamps, you may not have the same amount of hand-space between your fingers and the keyboard as with your original tray. With my desk's original keyboard tray, I would often type with my hands under the desktop, now the tray must be fully extended or my fingers hit the bar.The tray is sturdy and stable, made of a solid-feeling black plastic, and the clamps are solid, black metal. The tray is slightly smaller than the desk's original, but seems to be about standard size for a wooden desk tray: it has just enough room for the keyboard and mouse. If you're looking for something you can also put a small notepad or other item on in addition to your keyboard and mouse, this will not allow for doing so. The surface of the tray is lightly textured (in my case, this meant the rubber grip on my keyboard wrist pad is not sticking to the surface, requiring repeated adjustment).There is a dull white TechOrbits logo on the left-hand clamp, if that sort of thing bothers you. I don't spend a lot of time staring at the clamps, though, so this sort of branding isn't really an issue.I have only owned this product for a few days, but am so far impressed with its stability and sturdiness.Easy to install. Works great.Mounts securely to my desk and is very sturdy. Large size holds both my full size keyboard and mouse with pad. Slides very smoothly in and out on high quality metal glides.Note that the assembly instructions are printed on the back of the box and are not included inside. I didn't notice this until after I had assembled the keyboard tray. Very easy and straightforward to assemble... even without the instructions.I like the weight and stability of the MDF tray - it is much more sturdy than my previous plastic tray. After three days of usage this seems like a high quality keyboard tray that is well worth the $60 price.Sadly this really looks tacky on the desk and I wish I went with a permanent option. Further in the picture it looks like the clasps are silver, but in fact they are also white and there's an ugle "TechOrbirts" logo on the front. NOT AS ADVERTISED! Buyer beware this is a sturdy tray but it doesn't look like the ads.Update: Broke after a year, completely collapsed while I was working and the little feet scratched my desk really badly. Reduced from 2 to 1 stars. However the company did refund me so one star is retained for that.Au départ, j'ai acheté un produit similaire de ErgoActive que j'ai adoré. J'ai vu une autre utilité et au moment où j'ai placé ma commande, le produit ErgoActive, moins cher, n'était plus disponible (ce n'est plus le cas ...). J'ai donc acheté ce produit. À la réception, j'ai trouvé la tablette assez lourde. Le système de glissière est "questionnable". Il semble balancer. Lorsque déployé, les longues glissières dépassent à l'arrière de la tablette. La stabilité de la tablette n'est pas celle du produit ErgoActive. Donc, à choisir, c'est ErgoActive ... à moindre coût.This slider drawer is beautifully made, feels solid and sturdy. The clamps are of heavy gauge steel and they grip the table well with no play or unwanted movement. Remember to add a couple rubberized pads under the top section. The bottom clamp surfaces come with rubberized pads but the top do not. The drawer slider is reasonably smooth without being finicky. Installation takes 15 mins and you’re good to go. See attached photos for details.The brackets and slides are a nice solid metal construction. The keyboard shelf itself has a nice beveled front edge. Easy to assemble and install. As others have noted, there is no rubber on the inside of the clamps to protect the desk, but 1 cent worth of drawer liner cut to size solves that problem easily.
