I recently bought a Sekonic L-778 spot meter from KEH. On arrival it had an intermittent fault that became progressively worse. Since I live half way across the world from them, return shipping would not have been very economical - let alone the hassle of having to claim back the customs import duty I had already paid.
I emailed KEH and received an immediate response from Chris Brooks. He has been fantastic and has gone out of his way, and well beyond what he was obliged to do in terms of KEH's terms of service, to make things right for me, at considerable cost to the company. It's been an absolutely "no-quibble" experience for me - not "well it was working when we shipped it" (which I'm sure it was as it was initially an occasional intermittent fault); not "ship it back at your expense and we'll look at it"; not "are you sure you put the batteries in correctly"; just "sorry you have a problem, let me help me sort it out for you". I'm truly impressed by and grateful for the service I have received.
