Hello Everybody, after reading several bad reviews, I have given the curling iron still a chance. To my hair not colored or tinted, rather smooth, long and fine. I've used for styling of the John Frieda curls Heat Protection Styling Spray. According to the description I have to use for my hair only low heat level. At the low level, the tips have just slightly bent. At the highest level there were so-called "Summer Waves". However, only after the rod has been applied for about 30 seconds. The waves were then but also relatively quickly out again. But since I know not whether that can not also be the styling spray or hairspray. Conclusion: not really suitable for curly hair, who likes to wave's is perfect. For me it is a return.
