Review title is Best lenght alternative to fiber. [SEP] Love the length it provides without going to a fiber mascara (fiber is so difficult to separate lashes before it dries).  It does get clumpy after the tube is used for about 2 weeks, so I use a clean mascara wand to clear the clumps, after I apply it.  The waterproof is good but bottom lashes tend to wear off, likely due to the make-up I use. Due to how light my lashes are, I need to apply on both sides of my upper lashes.  It's still one of the best mascaras I've ever used.
