Ware wie ausgeschrieben Reibungslose Lieferung
Alles Bestens, vielen Dank. Lg, Philipp
produit livré assez rapidement, Produite conforme à la description Pour une 1 ère expérience tout sais bien déroulé
Normaal schrijf ik geen reviews, eerst was ik weigerachtig vanwege de lage prijzen tegenover België. Dan toch op basis van andere reviews aantal airco’s aangekocht. Van het eerste moment tot levering nog geen week later werd ik continu op de hoogte gehouden. Belde een transporteur netjes voor levering. Goederen waren goed ingepakt, geen schade. Ik zag dat ze meerdere artikelen hadden en bezoek de site zeker nog eens.
Rapide et bon rapport qualité prix
Alles in Ordnung, Lieferung dauert etwas länger.
Alles Super gerne wieder
Sehr schnell geliefert und der Preis ist wirklich super. Gerne wieder.
Fue un servicio rápido y profesional con un buen precio, en otros sitios salía mucho más caro.
Alles super, etwas später ausgeliefert als angegeben, aber per E-Mail wurden Anfragen beantwortet, die Klimageräte wurden einwandfrei ausgeliefert. Der Preis war unschlagbar. Es gab eine Sendungsverfolgung, DB-Schenker meldete sich wegen der Auslieferung. Alles super!!
Bon produit. Livraison rapide.
Ich war erst ein wenig skeptisch, ob das klappt aus Spanien. Ich habe mich deshalb entschieden ca. 50 € extra für Paypal zu bezahlen, falls etwas schief läuft. Aber es hat alles wunderbar und reibungslos geklappt. Ich bin sehr zufrieden.
Snelle levering en goed verpakt op pallet
