I see and feel no difference between the Gillette proSheild and Gillette proGlide Blades. I do however notice a smoother feeling shave with the FlexBall Tech. the pro Sheild cooling effect is different, but I'm not comfortable putting cooling agents on my face . Gillette does offer the better blade quality, but i see nothing special or new about this product, other than the flexball it's self.
