I have tried other "nano bond" type lashes more importantly, the liner...and none stood up to the test. They didn't make it through an evening. Lashies stood up to the 24hr test. In fact, using the Lashies bond liner, they lasted 3 days on (I put them to a little test run of my own to see just how far I could push them). On the third day, the inner corner of one started to come off. I'm completely fine with that since they are only supposed to be worn for up to 24 hours. These are certainly worth the additional money!
