Im using this product since long time and it is simply best. It doesnt smudge at least for 5 to 6 hours, rest depends on temperature and it doesnt come off easily either. After a time it smudges at the corners only but the entire line remains god.
It is easy to use and long lasts. it doesnt go messy even in rains, that is the reason I love this Kajal.
Its dark color makes intense finish and is definitely worth the price.
