Did not hold up as advertised.
I used these twice (2 round trips of only15 miles) and they were extremely bent.  I have a 62 pound kayak w roughly 15lbs of added weight and they did not hold up as advertised. I assembled them correctly and the load was perfectly balanced. These may be more appropriate for lighter duty use and I would recommend looking elsewhere for today's more standard weight kayaks.
