Sterling's # 387 the best thing since the electric shaver!

All brands of electric shavers work by the metal blades rubbing on the metal cover in a way that cuts your whiskers as you slide the cover over your face. The rubbing of these two metal parts is what makes it work and also what makes it stop working in many cases. Metal on metal motion needs lubrication to maintain both the range of motion required for cutting and can also provide for a much longer life of the metal cutting blades and foils ( or cover ). These benefits will save you both time and money!
