Although it is a fresh addition to my makeup bag, I have to say that I am quite satisfied with my choice, especially considering its cost (11€).
Nice packaging, nothing fancy.
Nice silicone brush with dense, large and small "bristles". It also has extra "bristles" at the edge of the brush, protruding parallel to the main body and not vertically like the rest, making it very easy to apply on the outer lashes. However, I think that due to its size, the brush will be more suitable for round and almond-shaped eyes, and not so much for a "cat-eye" look, as it is somewhat big.
The formula is average, maybe slightly on the wet side, and quite black. It dries relatively quickly and does not smudge under the eyes over time. Also, it does not have any particular scent.
So far, I am quite satisfied, except for the fact that because it is new, it has an excess amount of mascara on the brush, and I struggle a bit with the application because I am used to a thicker formula. Essentially, it applies more product on my lashes than I prefer. I solved this problem by passing a clean brush through them while they are still wet, thus removing the excess amount.
I should also note that it is a bit difficult to remove, which proves its longevity, but it bothers me because it requires a considerable amount of time to completely dissolve with makeup remover.
