I have spent the last four years now the fifth straighteners and it will probably stay that way. My hair is the worst there is, they are krizzelig, thick, long, curly and never beautiful. In addition, I have always mad volume. I've tried so many things, even permanent smoothing, but they held no more than two washes although they advertise with Affrohaaren and are supposedly permanent. My previous straighteners were all more expensive than 50 euros. But the big problem was that my hair was not smooth right and certainly not stopped. This trowel that will not break off the tips and hair loss I have not, though my hair is extremely damaged and stained and bleached several times. They are extremely smooth and keep for a long time, I can only recommend this !!! ;-)
