Ok in all the mascaras that I have used I rate this one being the best I've come across. It goes on and stays on all day even in rain I can feel confident that it wont smudge or flake off like most mascaras do after a few hours. It comes off really easily and cleanly which is what I love best about it. I find that for best volumising effect is to hold the primer/mascara wand on a verticle so you're only coating your lashes with the tips using an upward and outward stroke and then go over the lashes quickly with the wand on a horizontal as you normally do to even out the product over your lashes. The other trick is to know exactly when to apply the mascara after the primer has been applied (about 30 seconds) and apply your mascara in quick even strokes to prevent clumping as the mascara does dry up a bit quickly.
