Customer service was very helpful in making sure that I had everything I needed to adapt my fin to buy particular stand-up paddleboard. We went back-and-forth a few times before my order shipped and I was grateful for that. They also expedited my shipping so I got my fins in for the Fourth of July weekend so absolutely a big fan of the fan and everyone that sees it on the beach is like what is that? And I send everyone to you. Amazing product! Love it, very durable very high-tech very user-frien
