Title: ALSO brush head become loose after short period of time
Review: I don't want to rate even one star..... I bought a package of four brushes, and have used two. The brush heads fell apart after a very short period of time. If only the first fell apart, we can say it is an "accident". But what can we say if the second also fell apart even just after half a month?! I have to write this review here... And I will never buy this product from here again.
Is this product review negative?
