Very happy with this case. In the past I've had covers that deflated immediately in light winds. It fits my Volvo V70 like a glove. Covers at least half of the wheel completely. The first night I put it on we had a strong wind. He flipped my bike! No problem and I haven't attached the bungee yet. Can't speak to durability at the moment but it seems as well made as anything I've seen for what it's worth. UPDATE AUGUST 2015: Durability not so good. I'm not driving right now, so the suitcase was in the car 24/7. Definitely starting to glitch. He was torn, only by pulling was he taught. Very poor UV resistance. It will be like tissue paper. It will be a miracle to get out of it a full year.
