Review (5/5): That's fantastic as the steel isn't going to wear out any ...
Costs less than the nearly identical eyelash curlers you'll find at makeup boutiques *and* comes with 5 replacement pads. That's fantastic as the steel isn't going to wear out any time soon but the little pads do wear out eventually, fall off, get lost while traveling, and so on. Having that many backup pads (and at a lower price point than what you'll find at Sephora or the like) is great.
Further, it's spring action operated so it automatically opens after you curl your eyelashes (the unit includes a small sturdy plastic brace to lock it closed for storage and travel).
