I just started using this as part of my BzzCampaign and I am pleased so far. I have not been using long enough to tell how it will work for boosting lashes but the formula overall is great. The mascara goes on smooth and coats well. Best of all, it comes off really easy with eye makeup remover but has no flaking whatsoever and no smudging when you remove it. I don't know that the price of this will be in my budget but I am definitely going to explore the option of using L'Oreal mascaras from now on. I do hope the other formulas are much the same!
