I've only used it for a short while, but it feels very gentle to the face and it does seem like my pores have cleared up slightly! Will have to observe it for a longer period of time but so far so good! Only problem is that you've got to be really diligent in drying the brush. I saw a speck of mold a few days after using it althought I would squeeze the brush dry with my fingers and let it air dry thereafter. After clearing that speck I've been more diligent.. drying it with a towel and ensuring that I leave it in a well ventilated place / near the fan.
Spend less time to clean my face with the help of this brush, nice!
