I bought the E Fine quite some time ago. And now I've tested it. I've come to the conclusion that the E Fine [Patel board Aqua Marina] fits perfectly with the adapter. As a beginner, you shouldn't underestimate the E Fine. Even as a pro, I've fallen into the water quite a few times. I give it 5 points because the product is HIGHLY RECOMMENDED. It's a lot of fun. And when you don't feel like rowing, the E Fine does the job. I es tried es with two people on the board. It works perfectly and has enough power. Communication with the company is excellent, and they are very eager to help customers. Conclusion: I recommend the E Fine and would buy it again anytime. PS: I also tested the E Fine in strong waves, excellent thrust.
