I'm sure you've all heard of this product from Neutrogena. You've seen the commercial with Vanessa Hudgens, You've seen the advertisements. I'll tell you why it's worth the $14-$15 that it costs.
The package includes, the Wave itself, a free double A or triple A battery, and 14 single-dose cleansing pads. (When you run out of cleansing pads, you can buy more, 30 refill cleansing pads in all).
The gentle vibrations massage skin and open pores to help remove more dirt, oil, and makeup than doing ordinary cleansing. Apparently, after one use, skin is visibly softer, smoother skin.
