Overall I liked the racks. Unfortunately, some of the bolt heads were over coated on the smaller length bolts. I had a real hard time getting the allen wrench in deep enough to tighten the bolts. I tried both the included allen wrench as well as one of my own. The longer bolts didn't seem to have the same problem. I ended up cutting down two of the longer bolts to replace the shorter bolts that I couldn't make work.
