The new Flex Head Proglide Fusion razor is really exceptional. I was very pleased with my Mach3 for over 10 years and moved to this one a bit for the "sake of change", and much good has made me perfect glide and precise, impeccable sharpness of the blades and blade back very practical, successful. The price of the blades is a little high but they reflect the length, no need to change it too often. A real success!
