This straightener has three important advantages: 1) It heats in less than 2 minutes, but the handle stays cool and thus makes use of the device very comfortable. Only the inner plates roses rise in temperature; thus little risk of burns at least put his fingers into the clip! 2) The ultra slippery coating plates smoothes the hair without hooking the device to its full width and smoothes thicker strands of hair, but also to succeed as an internal or external to the movement of the hair. 2 runs on the same iron wick enough for smoothing curly hair; count 3 passes on crimped hair. 3) a head of the locking system in the closed position: what makes the slim, a small footprint, so really easy to fit anywhere. Personally, without being a pro flat iron or hair, I have never encountered a problem like "notched hair"; Indeed, when we talk "straightener" with other people who have already tried, it often makes us note that iron is smeared over when smoothing is made a stop or simply slow it. There, no worry of this kind! The wire length is quite sufficient. The device has an on / off switch with indicator light.
