Any of a hundred odd suggestions raised on here every year all of which follow the general idea of 'if this is a system why do I get to this part in the process and then have to resort to (bosch/dewalt/mafell/makita/other/noname) just to finish'?
The list is horrendous from systainer inserts missing places for very obvious items (CXS no attic lid ... REALLY?) or a huge multitude of bits that just don't exist in centrotec - spade bits - pilot bits below 3mm - hinge guide bits - a range of countersink bits with adjustable stops TC cutters and no marr rings - auger bits etc etc And yes I have many of these from 3rd parties trend (snappy) axsminster fisch but it is astounding that Festool develop a format with all the costs associated with that, make the case for it's superiority, and then undermine any possibility of it's success by not presenting a multitude of bits they could make yet more profit from!!!
And that's not to mention spare components and two new systainers designed to take two kits of bits say all the cabinetry related or a whole series of specialist sets VDE for example? It's not like wera and fisch don't make any of this already!
Their amazingly unteutonic lack of attention to detail is staggering and undermines the very essence of the 'system' they themselves don't really seem to understand. Anyway rant over... b r e a t h e : [big grin]
