They always strive to support customer requests to the best of their ability. When I encountered defective goods, they promptly provided replacement items and were very receptive to my suggestions for improving their packaging to prevent future damages.

    I have been looking for special power rectifier switching diodes that none of the many companies offering electronic components had not listed at all, or were showing several weeks, even months of lead time.
    When I asked Allelco for a quote, even for a diode they’d not listed, I got an instant response and a competitive quote for the parts not listed on their website.
    Allelco was accommodating regarding the payment method as well as the courier.
    On top, the sales person I was dealing with was very pleasant and courteous. Overall a good experience, will ask them first for everything electronic.

    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.
