Are Puffco accessories necessary, or can the device be used effectively on its own ?

Puffco devices are designed to work well on their own, so accessories aren’t strictly necessary for a basic experience. However, some users choose to add extras over time to fine-tune things like cooling, flavor, or convenience. It really depends on how often you use the device and what kind of experience you prefer. For a quick overview of optional upgrades and variations, you can always see more in the available selection. In general, starting simple and adding accessories only when needed is the most practical approach.
