The Gillete Mac 3 used to be really good when it came in first in India, sometime in 2000, if I remember right. But these days Gillete seems to be happy selling sub-standard Mac3s. It does go well for a while but it wearing off quickly.
At the rate of one shave per day, I have used the initial ones (in 2000) for 4-5 months per razor. At about 6-7 shaves a month, 3 months is only 21 shaves. 85 Rupees razor for just 21 shaves? Well... Not sure what to say.
These days, the new ones dont last that long. I guess the quality has definitely gone down. My shaving rate has not gone up.
But it is definitely a good product, considering that you rarely cut yourself when you shave. I have not done even once in the past 4 years. But at about 85 Rs per razor, it is not exactly the cheap kind of thing. Its the top of the line stuff. The question of cost-to-benefit is mute though.
The shaves are smooth, though I would not say that too emphatically.
