that schick quatro lasts super long for me... I am a cheap bastard so i signed up for like 100 free samples in the mail so i have like ashitlaod of both... Instead of changing blades, i just open up a new pack LOL. The quatro lasts sooo much longer than the mach.
But i have the same experience... no electronic shavers do the trick, unless its one of those $100+ ones, that dispense lotion and shit. if ur spendin that much why not just shave.. lol
