Mine are fine. I like the modular design, the racks essentially live off the boat when not in use. I have some surf, some wakeboard versions and swap them around depending on what we're doing. I found the surf racks to work well but they did not fit my largest board- a newer IS red which is thicker than most boards.. It's long enough I don't think I would want to stick it between two narrow prongs anyway.
I found them to be very solid and well made. I did have to drill and tap new holes to mount the brackets on a more sloping tower.
Overall I found them to be beefier and better made than the dbots I was comparing them to.
