This is THE curling iron to have in your bathroom. Ends of the ears or head burns with it no problem like this, it heats but no risk of burning. We must hold the said side (winder) to the head (it's written on the unit) to avoid getting hair pulling by the retractor. It is used on dry hair. For my part I have medium length hair and in 10 minutes I do the whole head for perfect curls. It is not too heavy and is silent, rendering is incredibly natural. The result lasts several days until washing hair, the curls are less tight over days but I am still wearing no need to redo every day. Well after that depends on the nature of hair, fine hair on the hair stands in time, it is possible that the thick hair that lasts a little less. Frankly it's a good investment for great styling and quickly too! I, who wore me not because of time and because-as the other device as long barbait me to use, I can not do without the Perfect curl so quick and easy.
