Title: okay for a single kayak; but not for a cargo bag
Review: Well, we tried it out by itself (in other words, without something strapped to it. It was noisy, but stayed on without an obvious problems. Tried it with a kayak tied down to it. Still no problem, but noisier. Then we tried tying our new cargo bag to it instead of taking the straps from the bag through the car windows, and it totally slid off the back of the car on the parkway going no more than 65. What a waste.
