I contemplated for a long time whether or not to spend the money on the Piston SR roof rack, and I ended up ordering 2 just to 'test' them on my car. I was using the Thule Topride, but also had a 1UP on the minivan.
The awesome thing about the rack is that short people like me can disengage the arms with ease. That is the reason why I went with these instead of the 1UP roof racks for this car. They were so easy to use, that I ordered 2 more for a full roof rack. Definitely expensive, but I only cried once. Happy to have them.
Excellent!!!
