Shave once a day or once every 2 days, you will not be disappointed. If you leave it longer, its not as good.
Having for 50 years bought multiple latest Phillips Shavers, this thing would not cut properly and their service Dept. did not want to Know or assist in any way.
It is the last Phillips product I will ever buy!
This was the most expensive shaver I have bought and I reckoned the more I pay, the better the shaver. This shaver just did not meet expectations. I needed to spend ages scouring my face in order to get a decent shave with this and it always left areas of the skin that it simply could not shave. After four months I have just given up with it and bought a Phillips Williams Special Edition HQ7390 and what a world of difference - and a lot cheaper too.
My advice, don't buy this, you will regret it
