Used a few times before switching to hitch Mount. Very secure and I've travelled to and from the mainland on the ferry without any worry. I have keys for the Thule locks that are built into the rack. Easy to use if you already have roof racks, or plan on getting some. Can be attached via factory t-slots if you have factory bars. Otherwise, I have Thule 52" bars also for sale that have t-slots in them. You just need the proper foot pack for your vehicle. These bars are $225. Paid approx $600 plus tax for these in total. My loss is your gain
