The reviewer, Caillet, tried the Lash Blast Fusion Waterproof Mascara in Very black color by Covergirl. They were looking for a mascara that would make their lashes appear longer. Caillet showed the brush and applied the mascara, accidentally poking their eye in the process. However, they noted a noticeable difference in length between the eye with the mascara and the one without. Overall, the Lash Blast Fusion Waterproof Mascara seemed to meet Caillet's expectations in terms of lengthening their lashes. However, the review did not mention any other specific benefits or drawbacks of the product.
