Super fast to install, would take about 5 mins to swap to your friend's car. Universal mount fits on any bars. Fast and effective loading of your bike.
Complaints: Cable lock is pretty wimpy. Rear ratchet strap needs to be longer, I can barely fit it around my 2.2 tires, glad I dont need it to fit around fatties.
