Should have read the other reviews about the temperature. To save you some trouble as to decide whether you are willing to deal with all of this, and also to remind myself how to use this, I am including the instructions from Customer Support here:
"There are the following precautions when using this product: This is because of the characteristics of wax after melting, and the temperature will quickly increase after the wax is completely melted. Therefore, we recommend setting the temperature to about 10 ℃ higher than the melting point of the wax, and then stirring continuously during the melting process, so that the temperature will be relatively stable; The temperature of this machine may have a positive or negative error, so it is best to measure it with another thermometer. Cooling should be done by pouring out the container and not placing it in a bucket, as the residual temperature after heating inside the bucket does not dissipate so quickly."
