He has necessarily a razor with cooling function is required, otherwise it will after shaving always looked like a crumb cake. Red pustules, rash - the full program.
With the built-in cooling capacity, he has this problem as well as not more.
It's also nice that the shaver cleans itself fully automatically.
A star deduction there, because the shaving performance is used to. You have to try out for a while until, on how to best use the razor to get a perfect result.
