I have thin and sparse lashes. The tiny brush allowed it to grab onto every lash - even the tiny ones in my inner corners. It's also very good for lower lashes as it doesn't disperse too much mascara onto it.

The formula is quite dry and the mascara dries very quickly. With one coat, I get good length. Two coats adds a bit of volume. This mascara isn't very build-able (to me - I don't like clumpy lashes) so it is very good if you are after a natural look.

I wore this for about 6 hours and there was no smudging (my eye lids are a little bit oily)

This is the best mascara I've tried so far and I will keep repurchasing this!
