My whiskers are particularly tough little things , not giving way to easily to conventional wet shaving as the blades glide over the top whilst going with the grain and dig in when going against the grain leaving a nasty rash. Foil shivers work but do leave a lot of uncut hair requiring multiple passes. The new 9000 prestige manages the toughest hair in the most awkward places like corner of mouth and under Adem’s Apple. This shaver whilst not cheap by any imagination, does give a nice close shave wet using shaving gel and also does a surprisingly acceptable job dry, without all the mess to clean up. Overall highly recommended. I have given all the other types of shaver I have tried away to my son.
