Bought three of these for my home office. Two for Synology NAS drives and one for a Mac Studio. The size ranges make this the perfect product to get everything off my desk. A little difficult to install with the desk upright so I suggest turning it on its side or over completely. In my case, I have these in sit stand desks which is great.

Decent bracket, Non-beveled screw holes cause complications

The screws that secure the mount to the underside of the desk stick out enough to cause the inner dimensions to change. I had to use the next hole down to increase the size of the bracket to accommodate my device, resulting in a less secure mount than desired. If the holes were beveled so that the screws fit more flush with the mount I'd be able to give it 5 stars. But the inner dimensions are not entirely as advertised due to the screws. Quality is up to standard otherwise, installation is relatively straightforward, price point is fine for a bracket of this size.

Great mount!

Great under desk NAS mount. Adjustable and sturdy, easy to install. Worked well for my Qnap TR-004 four slot DAS. I used 5/64 drill bit for the holes. Since my desk has a rear lip I reused rear stopper bit as a headphone hanger. I bend it slightly to a hook shape.

Tucks my NAS away

Sturdy and a major space saver. Worth the money to free up valuable desk space. Held my 6 bay QNAO NAS perfectly. Highly recommend.
