My granddaughter loves it!
I got the Neutrogena Wave Sonic Cleanser for my young teen granddaughter, who has been trying to keep some acne at bay. She tried several popular cleansers that seemed to irritate her skin, rather than clean and clear it. You perhaps could call any powered appliance for cleansing skin a gimmick, but if it keeps you regularly cleaning your skin, and the soap/cleansers are gentle and thorough, then I think it's a winner. The replacement pads are reasonably priced, and I have ordered them on the Subscribe and Save plan, which makes it very very convenient.
