Die Familie Kohler hat bei uns einen HWAM Ofen montiert. Wir sind ganz zufrieden mit der Qualität und Service. Frau Kohler reagiert sehr schnell, ist sehr freundlich und hat uns ganz gut informiert. Der Ofen war am Lager und konnte schnell montiert werden. Herr Kohler und sein Sohn Ennio sind sehr nett, arbeiten effizient und sind sehr kompetent. Wir können diese Firma sehr empfehlen!!
