Excellent iron with teflon coating and a microprocessor temperature control with an accuracy of + / – 1 degree. The temperature is set using the thermostat calibrated in degrees Celsius. Achieving the desired temperature is indicated by three LEDs. The condition for success is smooth, thoughtfully shaped body with Teflon coating that prevents damage to the balsa wood parts or scratch foil, reliable and accurate temperature control and light weight. Delicate point of each heating element is iron, which must be due to mains very thin coiled resistance wire. It is therefore important to work carefully and heated iron to protect against bumps and shocks.
