I bought it after seeing so many good reviews about this product. Since it is cheap on drugstore, US$19.79 after discount, i thought why not give it a try. When I received the product, my 1st impression is it looks cheapskate. the brush is soft, similar to my philips toothbrush, nothing fanciful. the 1st time i tried, i used it only on half of my face for 30s with the lower speed. i felt my skin being dried out after this use. then i used it after a few days, same drying feeling. I used it every few days, each time for half a face, 30s. After about 10X, there is no improvement in my pore sizes, they are still big & clogged.
