Ok I don’t know if I can quite call it buy it for life YET, but I’ve have a Philips One Blade for about 4 years and it’s great. My wife kept stealing it to shave her legs and we ended up getting her one too. Long battery life. Waterproof (can use in shower), powers through hair, and fairly inexpensive.

Not sure if it’ll last a decade plus but I recommend it. Good luck with choice
