This is a great fin and sensibly priced - but it's also the third one I've had to order! Despite using all three orange rubber stops pushed hard into the fin box, the fin has detached itself and slid back to a point where it has dropped through the slot where you insert it. Consequently I have now lost 2 fins and had to order one again. The solution however is simple - I now also use a standard US box fin screw and flat nut to secure it behind the rubber stoppers. So far so good :-)
