World voltage compatible hair straightener with LED indicator. I've only used this once since I bought it, and it comes with the instruction manual. Also, the power turns on with a long press and heats up to four levels. It heats up in about 10 seconds after turning on. - Model Name: HAIR STRAIGHTENER BRUSH - Voltage: WORLD VOLTAGE - Power Button: Yes - LED Indicator: Yes Please feel free to ask if you'd like to negotiate the price. I will lower the price as much as possible. Thank you for looking.
