When I first got the Gillette Guard I thought it was too mild and didn't cut well at all. Then I realized my mistake. I was making skin contact with the open comb, instead of the blade. I raised the handle a little and made sure that the plastic area above the blade and the blade were pressed directly against the skin and hair and then I got a very decent shave. So, if your impression is that it's too mild, try changing the angle to make the blade and above-blade area flush with the skin, which slightly lifts the open comb part.
