Five years and going strong!
I have been using these since 2020, and since I was coming back to buy one for my desk at work I thought I should write a review! This is ssincerely one of my favorite desk products out there. It helps reduce both shoulder and elbow pain and once you get used to using it, it feels super natural. Plus they hold up remarkably well, I've never had to replace one from wear ...

Does Not Stay in Place
I purchased this keyboard tray about six months ago, and it was easy to install. Unfortunately, it will not stay in place! I have to attempt to tighten the main knob continuously, but it will not remain in place. The movement is extremely frustrating and makes it unusable.

Short Track Keyboard Tray!
The short track is a game changer. We like a particular desk that only has 20" wide space underneath to mount, and this fits perfectly.

MI7135 could be better.
The metal parts of this keyboard tray and the shelf are well made. The slide is also made well (design is like a rack sslide and uses ball bearings).
The pieces I had trouble with were the threaded holes for the bolts that mounts to the slide. The holes were easily cross threaded and I had to drill 2 out and put nuts on the backs.
The other problem was the use of thread...

Exactly what I needed, but lacks comfort.
Easy to install and use, adjustments are very nice, great space saver. The ergonomics are lacking: small space for full-size keyboard and mouse, short vertical distance and no wrist padding. Works better with small keyboard and wrist rest.

Works great but have concerns!
Neck pain was the main reason I bought this item as my desk had under mount tray that pulled out but stayed very low. I was excited to try this and it does work great now that I can raise my keyboard and mouse up for my 90 degrees but after about 3-4 weeks I’m noticing the part that holds my keyboard/mouse is starting to lean, kinda tip to one side not sure if screws ha...

Just OK
Like it - don't love it. I wish it came out past my desk so that I could lift it up higher. It doesn't allow for lifting as high as the desk, or higher than the desk. The way that it is mounted requires that you cannot pull it out far enough to raise it higher than the bottom of the top of the desk. If you rest the weight of your arms on your keyboard it will tend t...

Easy mount
Was very easy to mount. My only complaint is it doesn't hold its upright position without retightening.

Good product!
Sturdy. Reasonable price. Quick delivery. Not too bad to install. It seems to be helping alleviate my pain from using my keyboard and mouse on my desktop.

Worth every penny. Well made. Great quality product.
It is well made and will last for a long time. Good price at Staples! I purchased it for my spouse who spends more than 10 hours a day at her desk. With the support of the armrest it greatly reduces her shoulder uncomfortableness and provides support for her elbow instead of having it dangling during her work hours. The design of the armrest is very thoughtful and it o...

What a relief!!
Got this because my arm is always stretched out and tore my ligament on my shoulder/arm. Since I got this I have a place to support my arm so I don't have to strain it. It's great just wish it had the mouse pad attached to it.

Sturdy but needs better tightening
This tray has a lot of heft to it. It was fairly simple to install; the instructions were clear. My only complaint is that it doesn't seem to hold its vertical position very well. No matter how much I tighten the bolt, moderate pressure on the tray causes it to gradually drop. Other than that, it's really well-made.

Short term - very good. Long term - we'll see.
I bought my first pair of these about 2 months ago and recently bought my second pair after having good experience with the first pair (I have two desks). I like the wide clamping area where you attach to the desk as it distributes the stress better than most others (I have a glass top desk). The adjustment range is good and the pad where you rest your arm is comfort...

Sturdy hardware. Keyboard area a little bit wobbly but not a deal breaker. Prompt delivery. Be aware that installation can be a challenge for the not mechanical types.
