Review (5/5): Effective, easy to use, great price
I've had this facial brush for a few weeks and have used it about half a dozen times. It definitely loosens dirt from my pores. I also use Biore facial strips once in a while, and now they seem to extract more crud. It's a bit messy to use at the sink since it flings water/soap around (especially on medium and high), so I use it in the shower. The fact that it's waterproof makes it easy to clean after using.
I like that it uses a standard USB charger and you can plug the cord directly into the unit, so that the charging cradle is optional. That helps if you're traveling with it. However, it'd be better if the unit used a standard USB-C connection so you didn't need the proprietary cord.
Note: The picture does not show the third brush provided in the box.
