My only worry about the Carvex 400 being classed a 'junk' is that it may be a relatively small number of people who have these 'rogue' machines. I am not trying to defend Festool, far from it, but I always aim to be fair. Has anyone asked Festool, or a representative sample of dealers, what percentage of old Carvex models were returned either for money back or for repair? If one were to read the various Carvex threads that have been here over the time that I have been a member you might think that 95% of the Carvex models produced were faulty. Human nature tends to ensure that on a forum like this the bad stories come to the fore and the satisfied tend not to bother getting involved.
But you are right, we have to get used to the fact that we are bound to be reminded, time and again, about the 400 series.
If anyone in the UK feels strongly about this then for a £5 fee one can lodge a freedom of information request to Festool UK asking what percentage of models sold have been returned. I suspect the figure will be much lower than some would be prepared to believe.
