I used these rack with a large Yakima carrier to Yosemite on my Mazda 5 and it worked great. I Purchased this product back in 2007 when I brought my first brand new vehicle. Not recommended for heavy duty use, works ok for storing natural corked wine bottles as well screw tops. I love these shoes they are light and they are super comfortable. I bought the XS and giiiiiirl this thing is addicting to wear. Extra sweat in the tummy area. The seams are poorly sewn, are fraying and the bag is now pulling apart. Upperfit (the name of the seller) sent me an email with these supplemental instructions:"IMPORTANT : If facing an issue with pairing, turn off both earbuds. It is working great now; but it took jumping through some hoops to get to this point. Does it’s job, sweat baby
