I received my White Caps from Brian in a weeks time and installed them last week. I had a chance to test them yesterday, the seas weren't high but I know I am going to like them.
It is a quality product and all of the hardware was included in the purchase including the screws.
I backed down yesterday to my anchor and Sure Marker Bouy, something I wouldn't have done before and they worked great.
The cost was $180 plus shipping.
