High-quality, high-value
Color: Black, Size: Fits Desk Leg: 80mm(D) x 50mm(W)
I was looking for something similar for my Uplift Desk for a long time, and gave up until I built a new computer and had a reason to resume the search. Seriously, this desk mount is top-tier; I'm coming out of a long drought to review this product.
The build quality, strength and stability is impressive, and assembly is easy. I'm confident that the stand could hold my body weight, let alone a computer. The appearance of the finish is high-quality, and color matches the coated steel frame of the Uplift desk flawlessly.
In terms of possible areas of improvement, I'd love to see a tighter vertical fitment of the top bracket's sliding arm, and I'd love if there were more rubber anti-slip pads and spacers of different shapes and sizes included. I ended up double-stacking the anti-slip pads, using superglue to adhere them to each other, to give my PC more breathing room on its underside.
I'd also love to have the option to select different sizes of base plates.

Great Quality Product
Color: Black, Size: Fits Desk Leg: 80mm(D) x 50mm(W)
Great quality and product was easy to assemble. Works perfectly for my sit/stand desk and precisely what I needed to get my desktop off the ground and to have it feel out of the way.

Sturdy mount
Color: Black, Size: Fits Desk Leg: 80mm(D) x 50mm(W)
Great product, very sturdy. no doubt I trust this mount/adapter to hold my 50lb PC.
Installation instructions were a little lacking in explaining what to do with the small black rubber pieces. Also, I feel it is very important to ensure the bracket is level before mounting the product - especially if you have a HDD inside your computer.
Nothing to knock a star off for.

Fantastic when paired with FLEXISPOT desk!
Color: White, Size: Fits Desk Leg: 80mm(D) x 50mm(W), Color: White, Size: Fits Desk Leg: 80mm(D) x 50mm(W)
I've got this to get my gaming PC off the floor, but keep it off the desk. It delivers. It fit my FLEXISPOT EC1 Electric White Standing Desk perfectly. This PC is 39lbs and there's no sign of it slipping or sagging under the weight as the base is sturdy. The top bracket isn't perfect for this uniquely size case. It installed in <5 minutes start to finish. I used an electric hammer-drill and it cinched up the proviced T-25 screws with ease. For me there's very little that I would change except for the top support bracket arm being slightly different sized.
