Review (2/5): Philips is a disposable product.
Great shaver when it was new. After a year they say to replace the head, but they do not sell the head any more. So for $100, you buy a replacement. The replacement sucks, and does not shave well. Philips is selling disposable shavers. After one year you get to throw it away.
Do some research and buy a more reliable brand that lasts a bit longer.
