As a helmet, it is very good and comfortable, but its application is half in Chinese and it doesn't adjust almost anything in its lights. It claims that the lights turn on when braking, but this simply happens with the use of a sensor that the helmet has, and not when it actually detects braking from the scooter through software, which means that the lights actually turn on either with the slightest movement of the head or if you crash.

Beautiful, lightweight, and easily adjustable to the size of the head by turning a wheel. Many lighting options. It flashes as you move and can be set to stay on steadily when braking. It charges easily with USB.
