Title: Lightweight construction!
Review: Purchased this to use with J-carriers to transport two kayaks. The product looks fine, but the base units are plastic, and the tie downs connect around plastic pins. The second time we used it, the entire unit broke away from the car roof (thankfully I was able to stop fast, and no one was following). It appeared that once one plastic pin broke, they all failed in short order.This carrier might be just fine for more lightweight transport, and perhaps even for a single kayak sitting flat, but it was a near disaster for my application.
