Today I sent back to 9090cc and use continue the 795cc I have since just over three years. The main reason is the shaving of not more thoroughly than the 795cc. For both it feels smooth after shaving equal to, ie before any progress. In addition the the shave of my old 795cc longer persisted as the new 9090cc. At first I thought I would but I just imagine then got it I tested it and one side of the face with the 9090cc and a shaved side with the 795cc, as it was then clear. At the side of the 9090cc stubble were significantly more likely to return and had to even harder than the other side. Why is that I can not say genuine because directly after shaving I felt both sides equally well shaved. Where the 9090cc is performs better with the volume, it is much quieter than the 795cc, there have also measured at 67 db db to 53. In the cleaning station, it occurred to me again equal aloud (not measured). Shaving feels with the 9090cc gentle on, however, after shaving the cheek side was the 9090cc noticeably warmer than the 795cc. Also comes the the "fan" in the cleaning station from 9090cc somehow not the bearer is, even if I've been waiting still for half an hour after the end of the drying process, he was still smeared wet and partially. The tapping of Scherr head was the 9090cc somewhat fiddly because the head is much narrower and could therefore hold him not good, always had the fear he slipped out of my fingers. So the 9090cc is certainly not a bad razor, but for a price of about 260 euros I expect that he is noticeably better than its predecessor or as in my case better than the pre-predecessor. For those who still an 795cc or even have a 799cc is not worth the switch in my opinion. But ... every beard is different :)
