Although it feels weird to poke your lashes with spiky tool that's twice the size of a regular mascara wand, I'll say this: it works. The formula is super-black and extremely shiny, and the brush lets you push a lot of mascara into the roots of your lashes, where you want it most. My lashes are long, but a bit thin, and Mega Effects definitely plumped them up. The Wonderbrush made reaching those inner-corner lashes tricky (it smudged), but that's what Q-tips are for.

Is it worth tossing your favorite mascara to try out? Probably not. But if you're in the market for a fresh tube, this one gets my seal of approval -- and not just for the novelty Wonderbrush.
