I have been using this Gillette Math 3 Blade since fifteen years. If you look at this blade, you will find that there are 3 blades in it. At the top of the blade you find a green lining. After some days of shaving, this becomes white. That means you have to replace it with a new one. When you glide it over your face, it moves smoothly without hurting you. The safety aspect is looked into. The handle is ergo shaped. So you can have a proper grip while holding. But from the price side, compared to traditional razor, it is very high. But it last longer, you get the real value for your money.
