I now have four years used a Arcitec, two years with the 10/50 Scheer head. With my beard has always bothered me that he has already received a 1.5-day beard on the length of her problems and the "smooth" shave took forever because the "long" whiskers were very difficult to catch. With the new Scheer head I no longer have these problems. The shaving time has whatever the beard length reduced to 1/3, the result / smoothness feeling is significant better and also the contour adjustment, I find the new head still clearly successful than with the old. In addition, I am impressed that no longer speisung alimentation three individual flaps to empty the catcher chambers, but now the entire lid is taken off and so a cleaning has also been simplified. Granted the price (at shaving daily. About every 5-6 weeks) is already not a small investment, but I am pleased that my "old" 10/50 Arcitec with still unmatched in my experience battery endurance with this head Scheer is compatible and so becomes a razor, I with the expected new pay 300 Euro. In my view, a very worthwhile investment.
