• Rapid Heat
Rapid heat like the name suggests means that the straightenr will heat up faster and therefore use less electricity. This also preserves the life of the appliance. Rapid heat can half the total time it takes to straighten your hair. You can also turn the aplliance off between sections, to save electricity, confident that the aplliance will re-heat in seconds.

• Adjustable Temperaure Control
If you find that the temperature of the iron is too cold or hot for your hair then an adjustable temperature is essential to control the irons heat. If your iron is too cool for your hair then its results will be less effective and last shorter. If the iron is too hot for your hair then it will dry the hair and the condition of your hair will deteriorate.

• Automatic Sensor Control
As with the adjustable temperature control except the temperature is set automaticlly by sensors in the iron.

• Switchable Temperature
The Dana Italia straightener has two fixed temperature settings chosen by a switch on the appliance. Better than no choice but not very flexible

Plate Size
The size of the plate determines how much hair can be treated in any one pass of the iron. Larger plates means a quicker action can be used decreasing the time needed to perform the straightening.

Voltage
Most electrical appliances will work on 120V since the heat of the plates is controlled by thermostat. The only problem is that some of the appliances will take longer to reach their operating temperatures at lower voltages.
We personally tested all appliances at 120V and all appliances reached their operating temperatures.
