The quality of an SKB rack can be split into the quality of the plastic, and the quality of the catches. I'm entirely happy with the quality of the plastic, it hasn't torn or smashed at all since I bought it. However the catches are something that can be massively improved upon. I use this rack along with a 6HE extender, and sometimes have to lift both sections together with the upper handles. These catches definitely have not stood the test of time bearing the weight of the lower rack across the four catches between the two racks. They are impossible to repair.
