    The fin design is nice, though quite thin. However, I received an item with poor manufacturing, full of little bubbles. See pictures. You need to quality check your items before selling.

    Nice, weed-resistant design
    I was looking for an inexpensive weed-resistant design for my 12′ 6 touring paddle board, and with it’s swept back design this fin has proved to work well. The weeds slide off nicely, but once in awhile I have to stop and clear a stubborn one. I paddled with a friend one day and she was jealous, as her normal fin was collecting weeds like crazy, really slowing her down. I didn’t want a surf style fin (the ones that look like a dolphin’s fin) since they typically have less surface area than is required for my board’s length. This fin has that bit of extra area that ensures nice, straight tracking… it’s really great in this regard. It’s decently made, and although it won’t win awards for build quality, it’s actually pretty nice for the price. I haven’t noticed any reduction in glide over my fancy $140 touring fin, if anything it seems a bit quicker. I have the RB-026 model, which is the clear version with the bamboo wood in the center. It fits perfectly in my US fin box, not too tight or too loose. It’s solidly constructed and feels like it can take some abuse. Overall, I’m very happy with it.’

    Fits, works, and looks pretty good.
    Good fin. Put it on my 7’8 mini log and punched as far back in the box as I could. Holds really tight lines, love the look, and am making it work. Wood grain and color is true in real life.

    Awesome product!
    Took a little long to arrive but we’ll worth it.

    Slow shipping and poor quality…. Not a recipe for success!!!
     I ordered this item with a specific delivery date. Not only did the item not ship until the original delivery date, when it arrived the screw for attaching the board is already stripped out and I can’t attach it to the board!

    Screw it arrives with is not long enough
    You won’t be able to install the fin with the screw that it arrives with.
