Operation is simple and intuitive, depending on the color of the backlight is the flat iron on the working temperature or not.
Also very successful, after turning off the display will show even if the flat iron is still hot, or whether it can be safely putting away already.
Not so great, I find that heating plates are kept apart. While the plates apart front behind a 3mm large columns (see picture). Pressing it with force together so remains this gap still 1.5mm high.
This requires a higher working temperature and multiple passes.
Compared I have a cheap WIK straighteners from the local retail bought last week, although this had cost only 20, it worked much better, probably because the plates are exactly on each other. The hair will equally smooth while they always get the Braun straighteners a slightly curved appearance.
