My Sigma Pro simply would not turn on so I immediately contacted Trusti Metrix by email on 6 February at 19:03. At 20:17, I received a phone call apologising for the delay (less than an hour), acknowledging my email and reassuring me on what they would do. At 21:14, I received an email asking me to try various things.On 7 February (Friday) at 18:35, I completed all the tasks but to no avail. At 18:59, they confirmed that I would need to send my Sigma back to them and that they would send a replacement out on Monday for me to receive Tuesday.I did, indeed, receive the replacement Sigma on Tuesday even before I had a chance to return my faulty Sigma. They are also refunding my postage costs.I'm not sure I have ever had such responsive after sales service from any company and they exceeded my expectations.Anyone in the UK thinking about buying a Sigma should buy from Trusti Metrix and not directly with Sigma (as I was originally considering). There is no way Sigma in the US could have provided a replacement Sigma so quickly.
