This statement because it only with difficulty does the job. The warm-up time is fine, but if you want to use the smoothing function, you have to bring a lot of patience!
You have to squeeze the device manually, so that the hair is smoothed at all. The distance between the heating plates is so large that it is impossible to take the hair and smooth. Thus, the smoothing to a long procedure. I can not make any statement about the other functions for the time being, because I have not tried yet.
Conclusion: So who smoothes his hair daily, should choose another device!
