selden el furex 300e broken after 3 summers

The stories about selden electric furl system continue. some years ago it took several months to get spare part to the main sail furlex motor.
3 years ago we installed an electric furlex 300e for the genua. this spring it died. opening it showed that it was full of water and all rust inside.
shouldt a device of this type have longer lifetime and at least be waterproof?

lets see now how long time it will take to get spares for this!!
