I have 2: a kneeboard/wakeboard rack and a surf/wake rack. Have had them for 2 years. They are fine and still look new.
They don't swing in, I couldn't justify the extra cost of that. But getting boards on & off takes some upper body/lower back strength as you will be standing on the seat and stretched out. My kids can't do it and my wife could but won't if I am nearby.
As far as the racks my only complaint is the wrapping method. They only come with a single bungee cord for wrapping both boards. Initially I would try to wrap both a kneeboard and a wakeboard with a single bungee loop....wakeboard would almost fall out. Had no tension on it. Now I could just be an idiot and not wrapping it right, but I tried every way possible and could not figure out how to do it. So to fix problem, I bought a roll of
bungee cord on amazon & made a separate strap loop for each rack position. But even with this I would not drive down highway with boards in racks. NO WAY! I have also taken my boards out of racks when water was
really rough as they were bouncing around more than I desired. But that was only once.
Mounting was a non issue too. When you order they ask what size diameter, but they send you several rubber spacer things anyway to optimize fit. It just clamps onto tower with 4 allen-head bolts. I put loctite on threads and they have not moved in 2 years. All in all they seem well made for the price but I have never had anything else to compare to.
Note:
kneeboard will not fit in surf rack.
wakeboard will fit in surfrack.
wakeboard will fit in kneeboard spot, but way too loose for any sort of speed/bumps.
Don't have a surfboard, just bought the surf/wake combo to keep my options open.
