I have now but had this Drehbox 3 months in operation and am now no longer dependent on them, because I have it with himself but finally turn out :) the Drehbox does now with my girlfriend of the smoke was a bit too expensive and on switched turn is faithful to their services! She still works properly and somehow I'd love to still use) as has already been written is the design and processing just great. I recommend you! I've operated with 6 and 8mm Filter, despite daily use (about 20 times) it still works like the first day
