The Heatle base and the wand communicate with each other via Bluetooth.
In the first step, the base transmits the temperature setting to the wand, and the wand in turn sends the temperature display back to the base during the heating process. A fluctuating temperature display, failure to reach the target temperature or continuous heating without ending the heating process indicates that the wand is faulty.
So that we can get a better picture, please contact our customer service. When contacting us, please have a picture of the front and back of your Heatle ready, as well as a short video in which we can see the heating process complete with rod.
