It isn't too hard to get it right when everything works exactly as it should (although some people manage to stuff it up even then). In spite of this, I reckon Ross is to be commended on his service.
The test is how someone performs when things go awry.
I recently bought a 2 micron stainless steel airstone from Ross. It arrived but was faulty. I bought the last one in stock. Not a problem for Ross. He telephoned me. We chatted for a while. He missed a hops addition to his brew (I wonder how that turns out). His system told me when new stock arrived, I ordered some more goodies and he sent me a replacement.
Problem solved. Except...
For some reason, I did not receive the airstone. I got everything else, but not the airstone.
I emailed him with the problem. He telephoned me. Of course he was puzzled - I was puzzled. If I were him, I wouldn't have believed me. He believed me. He sent me another airstone (all by itself). He was gracious and friendly all throughout.
So, Ross passes the 'when things go awry' test. With flying colours.
I reckon Ross is to be recommended on his service. To anyone who will listen. I've already told both my friends...
