i have been using a Whispbar rack and Thule bike carrier for the 2.5 years I have owned the car. Unfortunately the rack whistles even when the Thule is removed and it does not look good. I decided to try something different and bought the Seasucker. They have a distributor in Australia. This works as advertised and takes all of 15 seconds to remove and about 2 -3 mins to install including the bike!! Beware. There is a small learning curve! The Seasucker is a fork mount whereas the Thule is side arm. With a fork mount you preferably need 3 hands, and since we don't have 3 hands, you have to learn how to support the bike, and tighten the skewer with one hand. Doable when you know how. First time I managed to let the bike topple and it struck my head ( ouch), and the pedal scratched my hatch back ( treble ouch!!). The vacuum system is excellent and very stable. You need to ensure the mounting area is clean and dust free, easy to do with the supplied water spray bottle and microfiber cloth. Also you must strap the peddle horizontal with the supplied Velcro strap, or else it can swivel down and scratch your car in transit. Compared to fixed rack system, it is FAR more convenient though. Now, I have my rack and Thule carrier for sale. Private mail me if interested.
