content: At first glance this rack seems well designed. In fact when I first put it on my car it felt very secure. However, after 3 days I noticed that one of the inner arms was loose. On closer inspection I realized that the screw that tightens the arm was defective and wouldn't tighten. After pulling it out I wasn't surprised because the screw is made of plastic. I couldn't believe it. The entire rack was total garbage because of one plastic screw. The screw is not replaceable with something from your local hardware store either. It is a specialty screw with a large cap on it that lets you hand tighten it. I can't believe that Saris would do this just to save a few bucks. This rack went back to Amazon and good riddance.
