Great Product!
Worked like a charm!  Only thing that kept me from giving it 5 stars is the straps that come with it -- They didn't look as well-made as I wanted, and I had read another review that said they had failed on someone's trip and they lost their kayak.  This kayak rack was easy to install, simple to use, and mounted securely with no special tools needed.  I attached my kayak to the racks with two ratchet straps that I bought separately, and drove 325 miles. Neither the kayak nor the racks shifted a bit.  Arrived safe, sound, and in one piece. Great product -- especially considering the price! thumbs up!
