Overall this is an excellent product: the venting holes are spread over a very large area and are as as big as they can be, giving generous ventilation in crowded racks. My only criticism—and I'm probably just splitting hairs here—is that the product description only provides one low-resolution image that doesn't clearly show the painted finish. This lead to an expectations-vs-reality surprise, because I probably would have preferred a less matte finish. Indeed, the finish is a very grainy matte which you may or may not like. Overall though, the product is perfectly functional so I have no complaints.
