I've tried the device with a friend and then wanted it straight away. Here is now additionally the steam function. Can not tell if it really makes a difference. The disadvantage is, however, that one must keep it at the correct angle, otherwise the small tube through which is drawn the water is right in the bubble and does not absorb water. But if we have that out, that's doable. Another disadvantage is of course the price. But definitely worth it. Much better results than with curling iron and Co, it keeps a surprisingly long time, and handling is also very easy! So I would buy it again at any time.
