I do not know much, this is my first straightener, and actually, it smoothes my hair very long and already stiff efficiently. I guess he does not abuse it on delicate points in particular. Those of my hair is dried by lightening products and they become a little hard after the passage of the smoother and more dry, softer at all. Nevertheless, the hairstyle has a different look on the day when it is used and that its use is very easy: simply wrap the wick when the straightener comes to tips, and one can get a beautiful appearance curly, but not much. I therefore intend to use this little device in the "big" occasions. The value seems quite honorable.
