Review: As superb, quality float switch as is to be expected from Rule.
Review: ich würde sehr gerne 0 Sterne für diesen Schrott geben, was aber nicht möglich ist. Vorher war 15 Jahre der gleiche Schwimmschalter im Boot. Auch damals hatte die Bodenplatte aufgegeben. Diesmal nach 3 Monaten stand ein bisschen Süsswasser in der Bilge. Die Bodenplatte ist völlig zerfallen. Billiger und Schrottiger kann man so ein Teil nicht konstruieren.
