Straps Fail in Heat, Anti-sway parts don't prevent sway
Not a fan of this product. While driving in 120F heat, I had 4 of the straps fail, resulting in bikes swinging halfway off the rack on the freeway. I had to use spare tubes to properly secure the bikes.
The anti-sway devices don't work all that well. Wind can catch the bottom of a bike and swing it upward, even with the anti-sway strap well tightened.
The anti-sway devices also easily become detached if no bike is attached. I've lost two on the freeway.
