The reviewer, Ermina, shares her experience with the MICROMINI Makeup Sponge by Beautyblender in her video review. She mentions that the blending process was smooth and there were no creases. Although she initially found it a little difficult to hold, she quickly got used to it. The small size of the sponge proved to be beneficial as it allowed her to blend other areas of her face, such as the upper brow and inner corner of her eye. Overall, Ermina highly recommends the MICROMINI Makeup Sponge due to its efficiency and versatility. However, she does not mention any potential drawbacks of the product.
