Wow - this is all news to me...( but then I've only just started paying attention to the 370 posts on the board)
I'm saddened to see that this issue is raising its head with the 370s - I mean there is 'agricultural' and then there is simply not fit for purpose! At least we now have evidence that it can be addressed under warranty but if its just replacement with like for like who is to say this will not simply happen again and again?
