Nice if you want something simple, understated and suits the no-makeup makeup look. Great for lower lashes, as regular mascaras can make them look too thick. 

I have very fair and fine lashes. This coats them without clumping and gives a natural look. Also so far seems ultra waterproof which is a bonus because some waterproof mascaras still tend to leave smudges under my eyes. I will repurchase this and will be pleased if it lasts longer than the high end products I usually buy.

I'm giving this four stars just because I haven't used this for tightlining - but as a mascara/primer it's great. Adds amazing length and definition, no clumping at all. I apply one coat, let dry, then another coat and immediately follow with one coat of a volumising mascara - and my lashes look great. Recommended.
