This is the Concentrate Coil Attachment replacement for Randy’s Chill vaporizer. It has dual quartz heating rods within a quartz cup. The more coils the piece has, the more intense the heat will be and the faster it will heat up. It’s a good idea to have a spare atomizer before yours needs to be replaced. There is no specific length of time that your coil will last, as there are a number of factors to take into account. How often you use and clean the device and the product you put in the chamber will affect the period with which it lasts. Be cautious when depositing material as moving the metal wiring can cause the atomizer to stop functioning.
