Title: Completely useless and dangerous
Review: We used these to carry a kayak on top of the car. About a minute after hitting 60 mph, the kayak fell off of the roof and into the middle of the highway. Thankfully there wasn't anyone right behind us, and oncoming traffic stopped for us while we removed it from the road. What had happened was the straps holding the racks to the roof had frayed and broke. They are made of cheap and inadequate material. We ended up having to strap the kayak directly to the roof.
