This is one of the few products that I use that is not from Elf cosmetics. I'm a group fitness master trainer and have to present live workouts while still being made up so it was either find a good waterproof mascara or fight with false eyelashes. I've used several different mascaras and this one so far has been the best for the cost. I use the waterproof version called Butterfly. Often, waterproof mascaras have the unfortunate drawback of being very difficult to take off. Not only does this waterproof mascara serve the exact purpose that I'm using it for but it's not too hard to take off at all. And it definitely lengthens my lashes and gives that feather winged look to them.
