I prefer the Gillette Sensor Excel… two blades. For me, it’s superior in comfort, cut, and maneuverability.
I’ve tried the three, four, and five blade rigs – with and without battery-driven vibration. But always come back to the Sensor.
I just took a quick tour on the Gillette.com web site… and see no reference to the Sensor Excel anymore… the fewest blades is now the Mach 3. However, it looks like Walmart.com is still listing refill cartridges. Time to stock up!
