I've tried this on two different people and anxiety aside it works perfectly! Yes, there are horror stories out there about perming eyelashes but following the instructions and watching their official youtube page about how to properly use this product it worked perfectly.
I do wish the applicator was a different tip instead of the brush to provide a more even and continuous application but we had plenty of cotton swabs around so no worries there. Definitely would recommend this but make sure to follow the instructions!
