I let myself be tempted by this purchase given the very attratif price compared to that of in-store brushes. However, I regret my purchase because the quality is very mediocre. Comparing the new brush to the old I wanted to replace, the product is slightly different visually ... less white color, the hairs are much less rigid and first brushing there are even some who are completely detached, and must force to push the brush. I wonder if it is not counterfeit or if the quality has become really deplorable. If this is the first case, it is better to pay the higher price for a good product that lasts.
