Nachdem die alte Waschmaschine uns viele Jahre treu zur Seite stand, hat sie ganz unerwartet den letzten Weg angetreten. Zwei Persiliusengel haben sie mit Würde auf dem letzten Weg begleitet. Dank der kundenorientierten und überaus kompetenten Beratung durch Herrn Andreas Zumstein, Inhaber der Zumstein Elektroapparate AG, und nicht zuletzt aufgrund des guten Preis/Leistungs-Verhältnisses, haben wir uns ohne Zögern für den Kauf einer neuen Maschine entschlossen. Dank dem ohne Verzögerung folgenden Arbeitsablauf (Demontage und Abransport der alten Maschine, Lieferung und Montage der neuen Maschine sowie der fachkundigen Instruktion) ergaben sich für uns keinerlei Probleme. Wir werden bei sich bietender Gelegenheit die Zumstein Elektroapparate AG (Herrn Andreas Zumstein) und seine Mitarbeiter mit gutem Gewissen gerne weiter empfehlen. Marcel Dübendorfer, 3855 Brienz
