    Sehr netter Kontakt, überaus freundlich und kompetent. Versand ging auch sehr schnell wenn man bedenkt wo die Ware her kommt. Versandkosten und die dann angefallenen Zoll Gebühren sind zwar schon etwas happich aber im großen und ganzen kann ich es nur empfehlen.
    Beste Grüße aus Deutschland 😉
