He has a total of 25 cm long and fits comfortably in your hand. It heats up rapidly within the specified time. The 5 steps I think you do not really need, because I use the lowest level of 160 degrees and that is already very hot. It shows even if one takes a little further forward unintentionally. The smoothing effect is very good, and then the hair feel soft and supple. The hair is still the next day.
They say:
"The exclusive thermal protection sensor in the upper styling plate continuously detects the level of moisture in the hair and optimizes the temperature, to protect against hair damage."
It was important, especially the extra heat protection. On the device itself will not be displayed and thus can not check itself. Now, I wonder how and whether that actually happens. I use as I said the 160 degree stage, lower is "really" no. And how should you pull the trowel maximum (depending on hair length) within a few seconds through the hair, as soon therefore optimize the temperature according to my understanding cool ???
I control myself down the temperature takes the least. 10 seconds. As long as one is with the trowel when styling the hair not!
Since I am skeptical about this feature here and by the manufacturer in the product description and instructions for nothing is explained, I subtract a star.
The straightener I can unreservedly recommend otherwise.
