I have been using this brush for several years (3-4), it is still in a great condition, nothing falls out of it, it's easy to clean it with soap, it dries quickly. Using the brush is okay, although the application takes some time.
When using the brush with a product it feels very gentle, the bristles are soft, and it feels pleasant on my skin. It works well for blush, even better for powders. It seems to me that this is a good brush to start with. If it cost half its price I would have given it 5 lippies, and I would like to buy it again. But when I take into account the real price, it is a 4. I think that it's possible to buy brushes of similar or even better quality.
