Great piece!

The e-Fin easy to install! Screwed on the US box adapter, inserted the fin into the SUP, and secured it with the fin screw. Attached the remote control to the paddle, switched it on, and off es went. The different speed settings are cool, and the battery level indicator is also good, so you still have enough energy for the return trip after a full-throttle adventure. The reverse gear is also great. I can only recommend this product! Testosterone was Lake Garda in the windy northern part, where this fin is very useful in headwinds!

Fin 2.0

The fin is very well made and easy to install. All necessary accessories are included in the package. Delivery was quick and problem-free. The transport cases for the fins are also very good, allowing the fins and accessories to be easily transported and stored in the car, providing excellent protection. JayKay's service is simply outstanding and deserves 10 out of 10 stars. Best regards, Markus
