Query: Useless!

I would have given it a zero star if I could.- The unit keeps turnig off or changes the set temperature. The on/off and temperature buttons are so sensitive that with just a light touch the unit either turns off or changes the setting. Because of the locaion of the switches on the handle, it's impossible to avoid touching them. I accidentally turned off the power every time I curled a section of hair.- The end tip is too hot to hold. You could burn you fingers!I'm returning mine. I can't find a bettter way to hold this iron properly without turning off the unit and burning my fingers at the same time.
