I buy this mascara long with Urban Decay's "Cannonball" Mascara regularly - as soon as it's out, I have to restock. That being said, I'm slightly wary of, and haven't tried out many of the lesser known/drugstore brands since this is a product used near my eyes. In terms of the mascara itself, it doesn't clump if you use the brush correctly, and it will NOT smudge after you let it dry. It also dries on your lashes quickly and doesn't leave you looking like a raccoon if it happens to be humid or 90 degrees out. It doesn't come off instantly but it isn't difficult to take off either. I continue to buy this more pricey mascara over drugstore brands because one bottle will last me for a good while (though I know you're supposed to replace each tube every 3 months..) and I believe in investing in quality products, especially when it comes to eyeliner and mascara.
