I've used the Max Factor Lash Extension Effect non-waterproof version before and bought the waterproof one after my old one dried up.

I love using this mascara, it really gives your lashes a lot of length and when they say its waterproof, they mean it. This is my go-to mascara for this summer heat and even when I'm on the beach. It stays put all day, doesn't flake off and keeps your lashes looking long and separately until you wash it off with waterproof eye makeup remover.

It does not clump at all, and I would say a good 2 to 3 coats of this mascara will give you long, beautiful lashes. For me, I first apply a thin layer of this mascara after using my eye lash curler before I apply the next 2 coats so that the first coat holds the curl instead of weighing it down.

I love the brush of this mascara. It is long and flexible so it is easy to reach for all your lashes, even the ones on your bottom lash line!
