I use my razor in the shower, so no foam, and before I had 3 because the extreme disposable shavers were more expensive and no more effective and durable. I was on average 1 month or 2 with a razor extreme 3. and there during a promo I'm tempted by this one which corrects the main defect of the extreme 3: the back is wide open to let the water and thus remove the residue! Result: This razor is a behemoth of life! a blade = 4 months !!! for the thing to be done is aloevera the mail 3 months before but it shaves still good for the next 3 months! and with the support provided is perfect ...
