Review on VIVO 4 Inch Heavy Duty Grommet Kit for Desk Monitor Mount Stands - Sturdy Grommet Mount with Hardware, PT-SD-GT01D, Black by Maria Fukushima

This hub bracket is solid and does its job. Remember that the hub mount is compatible with any VIVO system you have. If you don't know which monitor stand model you have, you may have trouble installing it. For example, the grommet plate has three holes that must match the three holes in the VIVO stand. Well, not all posts are the same diameter, which means the holes will be positioned differently. The good thing is that the M10 bolt used in the gasket is (as far as I know) a universal bolt, so you should be able to do without the three bolts. I haven't used them in my build and it's holding up with no issues. There are no instructions in the packaging, so be careful. If you're reasonably accommodating, this isn't hard to understand, but it won't be for everyone.
