Admittedly, this was (mostly) an oversight on my part. Hence, I gave it 4 stars instead of 3. When I saw the picture of this mount, I "assumed" (Yeah, I know what that means...) it could be used to mount a variety of mini PC-type devices, similar to my new Beelink Mini PC. However, as indicated in the title - it was specifically designed for a Caldigit TS4 - which (I now conclude) is a couple of inches wider than a standard Beelink PC (4.5" square).Interestingly - the written instructions that came with the bracket show three brackets rather than two. At first, I thought I might have been missing a third bracket. (note: there was enough hardware for three) - but the picture clearly shows only two. If the third bracket had been provided, I could have made this work for the Beelink.I can't fault Brainwavz for my misunderstanding - but I also noticed that the dimensions were not provided in the description, which would have helped a lot (hence 4 stars instead of 5). The brackets are solid enough. They appear to be some kind of resin/3D printed design (the 3D layers are very evident). It came with enough hardware and clear written instructions. Unfortunately, I couldn't use it. Not right now, at least.
