The KR808D1 is a two piece system. There is an atomizer built into each cartridge, also known as a cartomizer. These cartomizers are disposable but can be refilled. You're using a fresh atomizer with each cartridge for maximum vapor production.
The KR808D1 produces excellent vapor, flavor and throat hit. This unit is also great because it has one of the biggest cartridges available. A new cartomizer can hold about 20 drops of liquid. And a used cartomizer can take anywhere from 5-10 drops of liquid per refill. Please note: Cartomizers are considered disposable so they are not covered under our warranty.
