Forgot to mention, an old riding buddy had the 4 bike NS, it had so much rust after 2 seasons he got rid of it. Not sure if that is still an issue. His road bikes didn't fit well on it either. For what it is, it has function and a simple, light weight design. IMO, $650 is a crazy price for what is provided. And from a direct only seller (no middleman/store). With a sale you can get a 4 bike thule setup for a similar cost. Then again, the Kuat and Thule are pricy too. Picked up my Kuat on sale for 25% off recently. Als.com always has 20% off and if you join their mailing list they give you vip access with great pricing. Having a lifetime warranty (Thule and Kuat) justifies the cost a bit. Had rusting straps on my Thule and they replaced no questions asked other than proof of purchase. My buddy contact North Shore about the rust, they told him warranty is only one year.
