The Sensitive blade seems somehow narrow at first glance, but a direct comparison with conventional blades shows that there probably is an optical illusion. They are just as big and wide, but just have a different color.
The mobility of the blade head back and forth is done virtually unnoticeable when shaving. The other, described on the packaging advantages listen to good, but can not be checked as a layman.
"Nice" is the reference to the box: "Up to 15 weeks Shaving in this package"
What exactly does that mean? A blade lasts 15 weeks? Or all together? If you shave every day? And if you use the shaver rare? I think grammatically would because a repair necessary.
The blades can be cleaned quite easily. Simply hold it under running water. When a couple of longer hairs caught between the individual blades usually helps a gentle tapping against the sink wall.
Caution: The blades fit all Gillette Mach3 handpieces, but not to other models of Gillette (only with adapter).
Conclusion: I use both Fusion Proglide and the Mach3 system. The first I would prefer due to the significantly longer service life of the blades. First, I give full credit for the peer-reviewed blades. Let's see how long you actually hold. Would report me again when I auffiele something negative.
