I have been using Isadora's Lash Booster Super Black for the past 4 years and I am OBSESSED with it. I have tried other mascaras on a whim, but I end up throwing them out because they simply don't compare to the Lash Booster. The wand doesn't have a brush tip like other mascaras do where they clump and get thick. Lash Booster has plastic-like brushes that always create a smooth application on my lash. My lashes always look long and natural, and never have any clumps. I will never use any other mascara, as I am completely hooked on this AMAZING product!
