I bought two of these desktop racks and couldn't be happier with them. They're made from thick metal so they don't bend under weight, the metal edges are finished well so you're not going to cut your finger while installing gear, they're the perfect size to fit on a medium/big desk, and even though they're not masterpieces of design, they're good-looking enough for most studios (definitely better IRL than in the photos). For this price, this desktop rack is a real bargain.
After trying a few other desktop racks and being dissatisfied with them (including the Thon rack, which was too big and grey instead of black, which clashed with everything else in my studio), I'm glad to have finally found a keeper.
To prevent these from sliding on the desk, I attached sticky rubber nubs on the bottom.
