I was reminded this morning why when recently testing out the shavers and "settling" on the 9 Pro why I made that choice. The misses was taking too long to shower on our way to work. I was able to quickly shave my head bald without worry of irritation. I did no creams, did not wet my head with hot water, etc. An Arc as is great as it is, can irritate the back of my head if I don't prep it. That is a reason why I returned that one and kept the 9 Pro.
