This mascaras brush is the best!! The packaging is lovely and shiny, funnily enough that actually matters to me. It seperates my lashes and doesn't clump like most mascaras do. You can pack it on and it still won't clump. Only been using this product for about 2 weeks so I can't really say whether or not the growth factor is working but all-in-all it's a lovely mascara that doesn't run or clumps.
