KT1 Ergonomic Keyboard Tray Under Desk - Under Desk Keyboard Tray Slide Out with Adjustable Height and Tilt - Easy to Slide and Swivel 360 Degree - Keyboard Drawer with Adjustable Mouse Pad

Wow, this keyboard tray is awesome!If you need a keyboard tray, especially for a desk that has a metal support rail set about 2 inches back from the edge on the bottom making it tough to find something that can both clear that and still be used at a comfortable ergonomic height when extended and in use. This fit the application extremely well!Observations when assembling/installing:The mouse mounting bracket did *seem* to be crossthreading when I put the screws in, but with the proper size Phillips screw driver its more of a built in lock washer effect when screwed completely in, just without the washer. I actually ended up using the washers on another project since it doesn't seem like they are needed for either the KB/mouse trays or the fasteners that screw in to the desk. Ill be shocked if any of them get loose as it IS a keyboard tray and not a jungle gym.Final impressions:Super solid construction provided you don't mount it on a 50 year old folding card table! I didn't think I would use the mouse tray, but I went ahead and put it on to check it out and its definitely staying. The single adjustment 'bike seat' lever makes it easy to move it down far enough to slide it under the desk when its not being used and is just as easy to slide back out and up to the height of my chair arms. This makes it super comfortable to rest your forearms on the chair while using both the keyboard and mouse. As an unexpected bonus they even included a mouse pad in the box cut to size, a nice addition to include as my washable fabric razor gaming mat is a bit too big for the area.------------------------------------------------------------------------------------------------------------------------My thoughts on other reviewers and their insane ramblings start here:I was kinda wondering if I had made the right purchase here after scanning through some of the reviews. Then I looked a bit closer and saw titles like "Dssign needs improvement" I had to do a double take based on nothing but the spelling alone. This particular reviewer went on to say the following:"Someone has to crawl under the desk and drill holes in the underside after holding the entire thing up to position it. Once you figure out where to position the plate that attaches to the desk, you have to disconnect the plate from the keyboard platform in order to screw it into the desk."Yeah dude, that's how these things get done.... what exactly did you expect? Did you really expect it to jump out of the box and magically mount itself while you fit in your afternoon nap? I assembled and installed it in less than 10 minutes with no help, and using nothing more than a hand screwdriver and a pair of pliers to hold the nuts on the bottom of the KB tray while tightening the screws. Then I held it up where I wanted it and marked one of the screw holes in the middle of the slide with a marker, then set the assembly down while I took my hand screw driver and put one screw in on the sharpie mark I had made. After that it was easy to just remove that screw, hold it up with one hand, and replace the screw which easily held it up while I was finishing the 7 others. I'm thinking some of these reviewers are JUST MENTALLY SLOW, because that was actually easier than I had anticipated! Before receiving and inspecting it I was sure it would need to be disassembled before mounting, but nope!This mental midget of a product connoisseur/reviewer goes on:"I don't know what other reviewers mean by 'easy installation.' It's NOT."LOL! They keep going on and on about how pathetically weak and clumsy they are, then proceed to speculate on what will happen when the rubber material 'wears off' (rips off because they are clumsy and whatever the opposite of intelligent is...):"the adjustment levers are tight and difficult to adjust." "And there is no lip around the mouse platform to keep the mouse from sliding off, which it does on a regular basis." "there is no lip on the keyboard tray either so it may slide off once the rubberized strips get worn down."LMAO!!! I can't even. Some people amirite? Talk about a total deficit of practical knowledge and skill. Too bad it seems to be more common lately... I wonder what happens when this individual gets a flat tire and no one is around to sing a soothing tune while changing it for them. I'd guess someone finds them in the fetal position in the back seat of their vehicle a couple days later muttering something about lug nuts and too tight... HAHA

This is the first keyboard try I've purchased so I can't say how others compare. I chose this, despite the low ratings, because of the Q&A where the manufacturer said this could be trimmed to size. I have a small space between my my table's legs so it was impossible to find something exactly the right size. I have yet to actually do this, but it seems to be a composite board so I don't see why I wouldn't be able to to trim and sand it.Installation was fairly easy, although the instructions leave a little to be desired. Because of my tight space, I had to mark the holes with the whole tray installed, which was tricky to do alone. It would be helpful if the instructions included a screw template for pilot holes. The instructions also failed to mention a few things:- When you connect the tray to the mechanism, you will need to use TWO washers, otherwise it will be very wobbly (instructions don't mention washers at all, but they are included).- My instructions said to use 6 screws to attach to desk, but in fact should be 8- There was no mention of the little plastic bumpers when it said to remove the bumper screws. Make sure you grab those so they don't go rolling away when you take out the screws.- There was no mention of the plastic pieces that go on the inner rails. Make sure you put them back on when you reinstall the mechanism to the railing. Mine barely fit into the rails and I kind of had to shove them in - but I think this is a good thing so you don't accidentally push in the tray as you're typing.- Instructions on how to mount the mouse tray were not very clear and could use an extra picture.I was very disappointed at first because even the slightest pressure made my tray tilt and fall even with the latch engaged. I realized that with the latch engaged, I needed to tighten the other end of the bolt. Hopefully this doesn't become a regular problem but is an easy enough fix if it becomes loose again. Would have been nice to have this in the instructions because I was ready to uninstall and send it back!Typing is slightly bouncy but I only notice it when i'm looking at the board, not through feel. Although I have issues with the mouse pad (see below), the trade off is that the keyboard tray is centered perfectly with the sturdy mount. I think on larger trays where you can have the mouse and keyboard on one tray, your keyboard would be off center and wobble more.The mouse tray is my biggest gripe with this thing:- Because it is so far off to the side, it wobbles a lot more than the rest - not a complete deal breaker but it is annoying- Even when fully installed and tightened, it sags off to the side. It is attached to the keyboard with long bars so you can adjust it farther away if you desire. The problem with this is that the holes that the bars go into are too big, so it hangs down a bit. The tightening bolt keeps the bars from sliding in and out, but it doesn't tighten them into a perfectly horizontal position.- The angling mechanism on the mouse tray needs some work. It is way too easy to tilt it accidentally with the weight of your hand.- A couple reviews complained about the mouse not being flush with the keyboard - those all appear to be older reviews for an older version. It is now flush (aside from the sagging issue). They should really update their pictures and video to show the new product.This didn't change my rating at all, but the tray had weird grease marks all over it. I'm not sure if it was used or just someone with greasy hands handling it before packing. Nothing a quick Clorox wipe couldn't get rid of, but still kind of gross.Note: one reviewer complained about the lower mechanism hitting their knees. This could potentially be a problem if you're tall and you like your tray pretty low toward your lap. I'm a 5'5" female and my knees are no where near it. If i'm in a weird position, I occasionally hit the bars connecting the mouse tray, but shouldn't happen in a normal ergonomic sitting position.Update: I did finally trim the keyboard with a table saw and and it worked perfectly. The edge is no longer black but could be painted if it bothers you. I’ve had the tray for about a year and I still agree with everything I said above. I’ve had to tighten the screws connecting the tray to the mechanism several times but the rest of the screws have held tight.

The actual base of it is pretty sturdy and mounts onto my desk pretty well.The rest of it is pretty crappy though. It's hard to slide. It's quite tilted. I used a bubble and found that the table it's attached to is tilted about 1 degree anticlockwise, but the shelf is tilted several degrees clockwise.I didn't notice at first that the mouse area is off to the right so I ended up installing it off center. That's on me, but that mouse area just feels a little flimsy.Overall, would not recommend, and I'm way past the return date so I'm going to go spend money on another keyboard tray that is hopefully a little nicer.
