@Valstybaby Yes! When I was young(er) I used to do that. Most people though have trouble telling when to stop and it is dangerous
I used to have an eyelash curler that heated up (battery operated). It worked great but over time (and constantly dropping it) had to be trashed.
I don't understand why someone else doesn't develop another one (battery heated). It would be a best seller because it would be easy to make it so it wouldn't get too hot.
After I junked that one I bought one or two others (again, supposedly battery heated) but they never worked so I gave up.
With the arthritis in my hands (fingers and wrist) it sometimes is difficult to hold onto anything too complicated. That's why I like the cheapie Revlon one, it's simple and uncomplicated (kinda like it's owner)...Ha!
