Duidelijke website met goede producten. Snelle levering goed te volgen via track & trace. Product is precies zoals verwacht. Fijn bedrijf om zaken mee te doen.
Materiale ordinato e pagato a un ottimo prezzo. Tempi di consegna come da accordi. Tutto perfetto.
Bestens alles geklappt. Besonders war die Sendungsverfolgumg. Diese wurde live geschaltet, somit wusste ich immer, wo die Sendung gerade war. Die Preise sind super. Sehr zuverlässig. Danke Aslan
Heel tevreden! Ik twijfelde of ik het wel aan zou durven om in het buitenland een airco te bestellen maar uiteindelijk toch gedaan mede omdat een airco hier goedkoper is dan in Nederland. De verwerking van de order en levering verliep buitengewoon soepel. Heel tevreden dus.
Quick, professional and without any problems.
Materiale livrate in termenul mentionat, impachetate inpecabil.
A única transportadora disponível no site, uso empresa sub contratada para entrega, tudo bem, embora encomenda veio com caixa inteira e funcional, a palete de madeira estava pedaço solta, ao abrir o ar condicionado, estava com EPS ligeramente desfeito, por que poderia ter sido por algum impacto, e dentro da embalagem tinha 2 pedaços de cobre com solda soltos. Na hora da entrega não assinei nenhum papel nem respondi nenhum código, encomenda de valor elevado e não tem forma de controle da entrega.
Délai de livraison sur le site erroné et non corrigé. Suite à mes demandes de remboursement sur des produits non livrés, le service après-vente ne répond plus... A fuir.
Great Service, great products, great prices. It took only a week to deliver to Germany with Schenker Logistics. Fully trackable, well and safely packed on a pallet, Highly recommended
