I used fusion and changed cartridges once a week, on Sunday in order to remember. I carefully rinse after every shave. More recently I switched to Magnum M5 at suggestion from this forum. Works as well or better at half the price.
Not to hijack, guys...but I have a suggestion..after you shave, clear the hair out of your blades and soak them in baby oil....I get an average of 3-5 extra shaves off of the same blade when I do this.
But when I only shave WTG it still feels sandpapery after. Is that normal? I fear that ATG will cause more irritations.
