Like other Jura owner I can not understand the high price of original accessories. For the price of four offered here water filter cartridges can I get the original not even three. And since our water hardness short of the "no filter" limit is scarred past anyway, it does not bother me even when these alternative cartridges should not bring all the power of the originals. What bothers me a bit that the fit for our Jura ENA Micro 9 One Touch does not fit 100%! I had to spend a little more strength to lock the filter cartridge in the holder, as in the original cartridge. Furthermore, the flow behavior has changed (which will be due to the slightly different design of the filter input), which, however, in my opinion, affect the flavor either on the quantity of coffee yet. Conclusion: Do not stop the original, but for the price a good substitute.
