Snelle levering. En goede prijs.
Bonjour commande reçu plus tard que prévu
Mauvaise expérience – à fuir ! J’ai commandé un chauffe-eau sur ce site et à l’arrivée, il était cassé. Le pire, c’est qu’il a fallu organiser le retour nous-mêmes, car le site de livreure n'a pas voulu rentrer en relation avec nous. Aucune coordination. Cela fait plus de trois semaines que nous attendons un nouvel envoi, et toujours aucune nouvelle, aucune réponse du service client. C’est inadmissible pour un achat aussi important. Service catastrophique , aucun professionnalisme. Je déconseille fortement ce site.

Apoio ótimo desde o início até ao fim da encomenda
Die Klimaanlage war wie in der Anzeige beschrieben vollständig, Bis auf die etwas längere Lieferzeit was für diesen Preis noch ok ist war ich sehr zufrieden, vorallem bei Fragen während der Geschäfts Zeiten bekam ich immer sofortigen support. Würde hier wieder bestellen
Bester Service, beste Ansprechpartner - Ich habe eine Thermor Brauchwasserwärmepumpe gekauft. Dies Modell war aber nicht lieferbar. Ich wurde sofort benachrichtigt und mir wurde eine gleichwertige, günstigere angeboten. Ich habe diese bestellt und wenige Stunden nach der Bestellung hatte ich den Differenzbetrag schon gutgeschrieben !!!. Als die Wärmepumpe geliefert wurde, war am unteren Rand eine Delle, die im eingepackten Zustand nicht ersichtlich war. Ich hatte nun Bedenken, ob diese Delle die Leistung des Gerätes beeinflusst. Eine Stunde nachdem ich dies angefragt hatte, bekam ich auch schon eine Rückantwort (dass die Delle nur in der Verkleidung war) und gleichzeitig das Angebot einer Erstattung für den kleinen Schaden. Dieser Service ist wirklich sehr sehr lobenswert. Sowohl die Reaktionszeit, die außerordentliche Freundlichkeit von Frau Laia Puig und die Großzügigkeit. Eigentlich müsste es 6 Sterne geben !!!! Vielen Dank
Produit conforme, livraison rapide
Ik wacht al 15 dagen op een elektriciteitskast. Ik had al 2x laten weten via E-mail dat de bestelling mocht geannuleerd worden. Toch wordt het enkele dagen later nog opgestuurd met levering over nog een week. Een Belgische website naar een adres in België, maar toch wordt dit vanuit Spanje verstuurd. 57 Euro excl btw verzendkosten en toch heel lang onderweg.
J'ai commandé deux groupes de climatisation gainable. Leur site annonçait un délai de livraison de trois semaines. Cependant, trois mois plus tard, je n'ai toujours rien reçu. L'avancement de la construction de ma maison est entièrement bloqué. Je vous conseille fortement, si vous construisez une maison, de ne pas commander sur ce site. N'ayant reçu aucune réponse de leurs part je vais saisir la DGCCRF et Europe Consommateurs.
des prix sont relativement corrects et intéressants. A recommander !
prix attractif et commande livrée en temps et en heure
Nickel !! !livré vite et sérieux et le temps nous dira le résultat du produit🥳
..alles professionell...
Sehr gute Nachverfolgbarkeit, zuverlässig, alles bestens. Vielen Dank
