Questions we are asked about build quality

How long does a unit of Vape Sourcing e-juice last in normal use?

For a typical adult user the answer sits between 13 and 22 days, depending on draw length and power setting. Heavy users will be at the short end of that range, which is worth knowing when you plan reorder volumes.

How do I check that a batch of Vape Sourcing e-juice is genuine?

Every retail unit carries a scratch code that can be checked against the production record. A code that fails twice, packaging with inconsistent print, or a price well below the normal floor are the three signals that should stop a purchase.

Does Vape Sourcing e-juice need any accessory to be usable on day one?

In most cases no, it is usable straight away once charged or filled. The two things worth adding at the point of sale are a spare coil or pod and, for removable-cell devices, a proper storage case.

How should Vape Sourcing e-juice be stored to protect shelf life?

Cool, dark and sealed. Heat and direct sunlight degrade both nicotine and flavour well before the printed date, and a shop window is the worst place in the building to keep stock for any length of time.
