I recommend the Shiseido eyelash curler.

This is the Shiseido eyelash curler I've been using ever since I first tried it a few years ago. I've tried all kinds of curlers, but none compare to the Shiseido one. I'm so clumsy that my eyelashes would always bend when I used other curlers, but with this one, they haven't bent even once, so I never have to worry about ruining my makeup. I bought several of them while traveling, and since I just replace the rubber tips and keep using them, I haven't even opened any of them yet. If you haven't found your perfect curler yet, give the Shiseido one a try. It's great!
