I have the trowel now about 3 weeks. The device has a switch to turn on to. Then shall you about 1 minute. wait until the unit has heated up. It is not displayed when the device is ready for operation, but after a minute each estimated it is hot and it works great. I have short hair, the curl in humid weather and are ungeföhnt slightly curly. If I after blow drying my hair smoothing it (I have a "Iroquois"), they hold all day super. Even in wet weather or light rain. I'm really excited. The acquisition was worth it !!
