Opinion 5/5

Zakupiony komplet siłowników do Liebherr 564 był w doskonałym stanie, zgodnie z opisem i przesłanymi zdjęciami. Obsługa na wysokim poziomie, bardzo profesjonalna i pomocna – rewelacja. Co więcej, w kontakcie z firmą otrzymałem osobistego opiekuna, który zajmował się sprawą od początku do końca, mogłem również liczyć na bezpłatne doradztwo przy montażu. Szkoda, że w obecnych czasach nie spotyka się zbyt wielu firm z tak profesjonalnym podejściem do klienta. Gorąco polecam.
