Puff count, for example “Up to 950 puffs per pod”, gives an indication of how many puffs a product will deliver, based on testing of the products at a set puff size. For non-rechargeable closed system products, such as Vuse Go and Vuse GO XL, this is based on the number of puffs the product will deliver during its life, until the product no longer delivers a vapour. For rechargeable closed system products, such as Vuse ePod, this is based on the number of puffs the e-liquid pod will deliver until the e-liquid runs out.
