I use this daily. Works for the entire day until I remove it. You can't even feel the weight of this on the lashes. Absolutely no complaints with my contact lenses too. And it's truly waterproof. Have shed tears with this but it didn't come off.
I really love my lashes after applying these eyelashes look beautiful give thickness to the lashes and also gives them the required curve..
This product gives really nice visible volume to my eyelashes without clamping it, I have tried many brands but this one is best till date.
