Review (1/5): Not good as expected
With curiosity, I also bought one following the trend, but the effect of this instrument to remove blackheads is not obvious. A lot of white things surfaced and the noise was very loud, and the nose was a bit numb because of the long time of rubbing. I don't like this. The marketing method of playing quantitative gimmicks does not have the effect of removing blackheads at all. It is purely foolish. Don't believe this method in the future. There is no scientific reason.
