My experience with them was not positive. Sent in my Bigma which I bought used with a Mack warranty. It was very soft, so I thought a simple adjustment would be all that was needed. They had it about 3 weeks before they contacted me - they said they were passing it on to Sigma because there was a warranty still active with them - even though Sigma warranties are non-transferable - about three weeks later they notified me that Sigma determined that it was not a manufacturer defect - time to cough up $350 to have it repaired or they would ship it back - uninsured no less. Another two weeks and to my surprise a new Bigma arrives in the mail.
Was it really not a manufacuter defect? I have no way of knowing. They make a big thing about being able to fix lens themselves, no evidence of this. Even if this deal was straight up - their customer service was terrible and it took forever. Bottomline, I probably would have done as well working with Sigma directly.
I'm sure that they have honored some warranties but I have never heard of any cases.
You might say what's the beef - you got a brand spanking new Bigma. I would say where's the beef - as far as I can tell Mack has never done anything for me. Until I hear that dozens of individuals have had a trouble-free experiece where Mack actually stood behind their warranty and delivered upon their promise - I would say save your money.
