I have been using my Adona Racks for quite a few years. In fact, Paul custom made one of my racks. I am quite pleased with them, they hold my equipment and weight quite well, are very well constructed, quite attractive, and not overly expensive for what they are. However, I do normally use some footers under my components (mostly Herbies) for even better performance.
Below is a photo of my 3 Adona Racks with installed components.
