I had previously a shaver of the brand Braun! This caused by the cleaning cartridges alone cost more per year than the HQ6990 costs. I must say that I am absolutely impressed with this razor. He is very quiet compared to my former Braun shaver and provides a good shave. Another selling point was the easy cleaning of the razor for me. You just have abnehmmen the shaving heads, and clean the HQ6990 with the brush and tap - finished. Redness does not even occur, because this shaving head system is very gentle on the skin. So I can only issue a buy recommendation!
