The cup holder is top. It is high-quality. The clamping force is very good. I especially like the torque support below. Also, the flow at the bottom of the cup holder shows that the company has made real thoughts. The price is more than fair. I would have 10, - paid for it. The cup holder is a day with a coffee mug in action with me; nix is shaking! I can only recommend! PS Even the packaging I found very good. A printed card on the cup holder is secured with a wire tie. On the box the installation manual is printed in several languages. Perfectly adequate and makes little garbage!
