Replacement works great!
Changed review:  The customer service department contacted me and sent a replacement curler.  It works fantastically well!  The first curler must have been defective.  The new one has two distinct settings that work at different temperatures.  Very pleased.<br /><br />It doesn't heat up enough to produce curl.  My eyelashes are very fine, and it doesn't take much, but this hardly heats at all on the high setting.  The low setting could also be called "room temperature."  This is the third, most expensive, and worst heated eyelash curler I've bought.
