The Panasonic ES4026NC Sonic-2 Pro Curve Wet/Dry Shaver has two fully independent floating heads to provide a close shave even on the sensitive and variable geometry of the neck and jawline. A man's face isn't a "regular" surface, and you need a shaver that can conform to your unique features. The floating heads adjust as you go, and two different speed settings are available for different parts of your skin. The twin heads lift and wash for easy cleaning.
