    The item I purchased was on pre-order when I purchased it but Sigma shipped it on the date stated. Well packaged item, no fuss at all on Sigma Coffee's end
  • ★★★★★
    Amazing customer service! Very fast with their response and products arrived very quickly. They also gift wrapped it with a card saying “Happy Birthday” as I left a note saying “a birthday gift for myself”. This small gesture literally made my day! Also I’m very pleased with my products!

    Very happy. Customer Service has been great, delivery to Northern Ireland was quick and free (something that has been more unusual since BREXIT), well packaged and the 1zspresso grinder I got was by far the cheapest I could find anywhere. Very happy will be using again
