I've bought a few things from Sigma now, including coffee and some expensive grinders, and the service has always been stellar. Recently I bought a Lagom Casa grinder on pre order. It got dispatche... See more

Good returns process
The grinder I ordered from Sigma was not quite as I expected (my fault :0) and the grinder was returned and I was refunded quickly and with no fuss. Highly recommended.

Stellar customer experience and product.
I purchased a hand grinder from these guys and was using it religiously to a point where I damaged a silicon gasket that comes with it. I got in touch with the manufacturer to get replacements and ended up opening a line of communicate between the 2. David was stellar in taking over the logistics and paperwork in retrieving replacements and getting them to my door step. I commend their dedication to extraordinary customer service. For the ease of use of their store, purchasing and fast delivery. Also their pricing from what I've seen are incredibly competitive. Better than Amazon which is often the more convenient option for most things.
I've also recieved 2 codes since so I've been spending more time browsing their website than doing anything actually productive! I'm planning to come back and make some more purchases in the near future. I might bother David again for the giggles.

Excellent customer service and after…
Excellent customer service and after sales care. Got a Varia AKU scale which was faulty and David was in communication straight away, sent out a replacement and then another when that one got stolen in the post! Excellent supplier and couldn’t recommend enough.
Awesome service!
I haven't even received my order yet, but wanted to say how good the service has been... messaged about changing my delivery option and got a response and solution offered within 5 mins of contacting them... 5 star service for sure 😀
The personal touch, the good products, and price
A very positive experience. I had been on the lookout for a better coffee hand grinder as my current one could not do the precision required for an espresso machine. After some research of my own and a discussion on the Sigma chat with David this was narrowed down to the Kingrinder K6. A good competitive price from Sigma and in stock when very few were available. The turnaround to the order was quick, and the delivery too. Subsequently, David has helped with follow up questions. Very happy with my experience with Sigma. The product itself is well worth it, I was surprised to find myself being prepared to pay as much as I did for a coffee grinder even though there are plenty cost even more. Now I have regularly used it I am sold on it, and it really enables me to "dial" in the grind of my fresh coffee beans and get the best results from my espresso machine.
Great Small Business
Tried Sigma for the first time as they had a well priced little coffee scale I wanted for my new espresso machine. Delivery day rolls round and Royal Mail claim to have delivered it, only to send me a picture of it outside the wrong house.
I got onto Sigma and within an hour David had resolved the problem, and even offered to replace it for me while they sorted it out with Royal Mail. Had my scale the very next day. Top company, top customer service. Would recommend.
Amazing and personal customer service
I bought a hand grinder from Sigma which really didn't have the grind consistency that I needed for my espresso. I opened up the chat function, and spoke to David almost immediately. I explained that the grinder I bought really wasn't doing what I needed it to do - not a problem with Sigma, but rather the grinder itself. David kicked in to action really quickly and offered a few ways to resolve and both on chat and email kept in very close contact as I resolved the issue and ordered a new grinder.
I judge smaller companies like this not on the successful purchases, but how they respond when there is an issue. Here the issue was with the grinder, not Sigma, but they bent over backwards to help me and gave me amazing customer service. I couldn't have aske for any more, and they have certainly secured my future purchases because I feel that if there are any issues, Sigma will help me resolve in a fair and fast way.
I would very much recommend Sigma, and hope that their attention to customers wins them many more customers.
Avoid - taken money no item
Ordered and paid for Royal Mail 24 - which on Royal Mail's own website means next working day delivery, or as close to it as possible, this company hadn’t even processed my order the following day, let alone sent out to Royal Mail.
I have now been told by 'David' at Sigma, Royal Mail 24 does not mean 24 it means something else and I should have read Sigma T's and C's why charge for 24 when it means something else - personally I feel the customer service is rude and unhelpful. I have therefore requested a refund as trust with this company is now lost. I have now found the product cheaper via an eBay seller and utilising Royal Mail 24 have a tracking number with a delivery date of next working day - I would also questions why most of their ‘positive’ reviews on here are from people with very few, if any previous reviews

Heroic Sigma Saves a Poor Fool
I made an absolute goof of myself by ordering the wrong coffee grinder. To make matters worse, I did it on a Friday and had the audacity to contact this team in the evening.
But to my astonishment, they picked up.
The name "David" came on my screen like a graceful angel descending from the heavens upon this graceless fool that is me.
David fixed my conundrum faster than you could say James Hoffman.
David had the warmhearted kindness of a mother who's tending to their ill stricken child.
David was like the friends we made all along.
And just like that, this hero disappeared into the almost night, very likely onto the next helpless soul like me which made a classic ordering blunder.
The bottom line: Sigma Coffee truly earned the name "Sigma" on this day, and probably long before I even knew them.
Really Impressed
Supremely fast delivery and excellent customer service. I’m really impressed!
5 stars
I ordered a bottomless portafilter from Sigma Coffee.
The item arrived on time, well packaged and item was of very good quality.
I would use Sigma again and recommend them to others.
