It arrived within the estimated time, well packaged.
The design is practical, you can carry it personally in your wallet. I recommend charging it for 24 hours the first time to protect the system; when plugged in, the three dots will flash and once charged they will stay on.
To turn it on or off, you press and hold the button for a few seconds, and to change the temperature (it has 3 temperatures), you follow the same procedure as if you were going to turn it on. To select the temperature, the first, second, or third setting will light up the dots according to the temperature you want. It doesn't make your hair as straight as a flat iron, but it does make it quite smooth. I recommend it.
