I use the Olay Regenerist Daily and the brush had since I have not ordered any replacement brush about a year ago half risen. After about 3-4 months, the brush already felt very scratchy. I was then ordered to lazy to new. Have it but made after 2 months. The brush feel super smooth and I find the price is also very good, because the durability of the brushes 3-4 months is (in my opinion).
