Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
It came broken. I opened the box added some batteries to find it was broken. I changed he batteries and the brush head still wouldn’t spin. Only vibrated. I changed the brush and the same thing happened.
Affordable price compared to other brands in the market. I have been using this for a week now and I like the brushes they are not too abrasive and I can use them everyday (except na exfoliating brush). HIghly recommended for those who have sensitive skin.
