But:
I have dared and have to say that I'm super-happy with the device !!! It really conjures up great curls in no time. My hair is long and about breast normal (neither very thick nor very thin) and with conventional curling iron is me unfortunately never succeeded. But with the Mira Curl it really sooo simple and very very fast and with a little heat protection lotion keeps it really two days. The curls are then although of course weaker, but still very nice!
The unit will beep and "lets loose" if there are problems when screwing.
Just buy it !!!
