Who, for example with a Saphire Funnel smokes head at a high level requires a Edelstahlmod. This succeeds every head. The draft has been optimized and it prevents the sieve / aluminum foil touching and burning the tobacco. Whether I think it is now 2 or 5 paid for the Mod matter because you only need one single forever.
Minimal drawback: under certain circumstances it may happen that the Mod is difficult to clean. Here helps insert in hot water and in very hard cases, pipe cleaners. Geschmacklick but no appreciable difference, if it is smoked with "dirty" Mod, therefore no deduction.
