Review (5/5): Hair so straight!
I used the straightener for the first time today. The temperature starts at 300 degrees , then if you push the button again, the temperature increases to 30 degrees with every button press, up to 420 degrees. Using the straightener was very straight forward. I straitened my whole head of hair in less than 10 minutes. I have thin and fine hair. This is a quality device made of good material.
