Using a lash curler always makes me feel a bit insane.
Really makes me nervous.
The Revolution still makes me nervous (steel pinching millimeters from my eye ball!), but at least it doesn't make me feel as though I am sending my eye to prison.
The cage-less design is really cool, makes the whole process easier.
Gives the lashes a good upturn, not a harsh bend/crimp.
If you don't have naturally curly lashes (who does?), this is the next best thing.
My only negative issue-- the little black rubbery pad has a tendency to fall out. I have to keep it in pinched-mode with a hairband while traveling.
Worth the price, the scare, and the hairband, though!
