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.

Great Buy
Instal was easy and it seems good so far. I need to cable manage and everything but other than that it is great. Just wish they put Rubber on more of the metal parts so it doesn’t scratch the pc case.

Great way to keep your desk organized, especially a standing desk on wheels.
Color: White, Size: Fits Desk Leg: 80mm(D) x 50mm(W)
The knob that should be able to tighten and clamp the upper part of the PC does not fit into the hole on the metal plate, so it won't hold the PC securely in place. It's useless.
Updated 2/18/2026
I contacted the company about my issue and they sent me a replacement surprisingly fast. The knob on the replacement fits perfectly and my PC now sits securely on my desk leg.
