Ease Of Installation

Sturdiness

Loved this product and amazing customer experience!

Fantastic keyboard mount!

mount-it.com

I love this under mount unit. It was easy to install. Just mount guide frame first for hole alignment check. Then remove guide frame, install arm to frame and remount mount under desk. Then install key board guide why sitting in your desk chair with 4 easy screws. It solid and sturdy. You can adjust the height of the board for your fit. An added feature (which I did not realize when I ordered it), you can rotate the key board either direction (pivot point center). This has come in real handy several times in the short time of my use. I wish I had done this earlier. I didn't realize how much more comfortable of typing at below desk top level is. The pad that comes with the board is a nice feature comfort feature. I would buy this unit again and highly recommend it.

I love this under mount unit

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.

Short Track Keyboard Tray!

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.

Sturdy but needs better tightening

Metalwork well executed,  must follow installation order.  Platic was too wide for my application.  Need to retighted adjusting know often.

Better than anticipated

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 threaded screws for pivoting up and down. This leaves a lot of play in the tray even when the knob is tight. I drilled those holes out to 1/4” and put a 1/4 shaft in their place. Much better.
I have no issues with how far it is below the desk. It cleared my knees easily.

MI7135 could be better.

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 to lower under the weight.

Just OK

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 have gotten loose or what but wish this wasn't the case cause its making it hard on my neck again and I don't have packaging anymore and can't return it if I can't get this to fix.

Works great but have concerns!

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.

Exactly what I needed, but lacks comfort.

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

Easy mount

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.
