The product itself is great. Far improved over past models with both the stop that keeps the wheel secure and the device which keeps the wheel from spinning.
That said I wish the website would have had dimensions for the mount. With two bike mounts and one kayak mount on top of my Xterra, I had a hard time fitting them (I bought two) on because they were wider than I expected.
Anyway, excellent product. Just make sure you have room on top for the product.
