Replacing for free might have been the best in terms of PR but its one of those commercial decisions.
it sure is. Nicolai’s cost would have been a couple of hundred euros at best. For that they would have had a loyal customer who was likely to extol the virtues of their brand and may well have bought more frames, or at least recommended the brand to others. What do they have now?
I know there are probably scores of people who chance their arm with things on warranty, but if both sides of the story are correct then a simple gesture by Nicolai could have resolved this without a thread bemoaning their warranty process.
edit – re-read the OP and their 130 quid replacement could have been offered as a goodwill gesture at the outset, which imo would have probably gone a long way to avoiding this thread in the first place.
