The reviewer, Kennedy, is impressed with the Bye Bye Panda Eyes! Vol. Def. Mascara by Essence. They applied three to four coats and removed any excess product. They compared their natural lashes to the $5 mascara and found a noticeable difference. They also compared it to their regular $10 mascara and highly recommend the Bye Bye Panda Eyes! Vol. Def. Mascara. Kennedy's video review suggests that this mascara provides volume and definition to the lashes, surpassing the performance of more expensive options. However, the review does not mention any potential drawbacks or specific benefits of the product. Overall, based on Kennedy's positive experience, the Bye Bye Panda Eyes! Vol. Def. Mascara by Essence seems to be a worthwhile purchase.
