  • buttons 203 may be placed into a ‘locked’ mode wherein their functionality is disabled so that a user does not inadvertently adjust the performance parameters of the adjustable curling iron 100 during use. The buttons 203 may then be ‘unlocked’ to resume normal functionality. In some embodiments, one or more of the buttons 203 may be ‘locked’ and ‘unlocked’ by toggling a mechanical switch. In other embodiments, buttons 203 may be ‘locked’ and ‘unlocked’ based on a pattern of button presses.
  • pressing and holding the power button for a short period of time (e.g., between 2-4 seconds) or pressing the power button in rapid succession (e.g., quickly pressing the power button 5 times) may lock/unlock the mode and ‘+’/‘ ⁇ ’ buttons.
  • the buttons 203 may automatically assume the ‘locked’ mode after a period of inactivity has been detected (e.g., if no button 203 is pressed for 1 minute).
  • the heating rod 300 may have a first end 301 and a second end 302 , and may include a housing 303 extending from the first end 301 to the second end 302 .
