Good grip, you can adjust the intensity of the heat, the unit heater immediately and the red indicator light tells you when it is ready for use (the light stops flashing and remains lit). Not complicated to use, you get beautiful curls in no time and you can work well in detail. Thermo-resistant gloves are provided with but I do not use it because I am no more accurate. If you do not use gloves, be careful because the device is really hot and you risk burning your fingers. I do not regret this purchase.
