Joe if you have problem of irritations after shaving, I would suggest you to try with a shaving gel, rather than shaving foam.
I’ve started with the electric razor some years ago, and used it for 2 years and a half. It satisfied my main requirement at the time, that was a quick shave every day before getting ready to go to school, six days a week. Unfortunately I had pretty bad irritation, especially the Monday if I skipped Sunday morning.
I’ve used a 3-blades Gilette razor for a while with shaving foam, but that didn’t actually improve the situation; it mostly stopped irritating when I moved to the gel.. the bad thing is that the shaving gel costs way more than foam (although it usually last more).
