I am shared on that product. I does what it say: it does not budge, at all. It is even though to remove with an oil-based cleanser. It is also blacker than black and does not flake during the day. That being said, I HATE waterproof mascaras and I haven't find one that I love yet. Unfortunately I kind of need it during allergies seasons because my eyes get really watery. Like other waterproof mascara, the formula is thick, a bit clumpy. Hello big, black, crunchy lashes from my high school years. I appreciate that this brand is cruelty-free and Canadian, but I am looking forward to go back to a non- waterproof formula.
