Questions we are asked about MTL versus direct-lung style

What causes a burnt taste with Vape Sourcing e-juice?

Nine times out of ten it is priming. A coil that has not been saturated before first use, or a tank run dry, will scorch the wicking and that taste does not go away. Fitting a new coil and waiting a few minutes before the first draw prevents it entirely.

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.

Are there different versions of Vape Sourcing e-juice for different markets?

Yes, and it matters. Strength ceilings, bottle sizes and notification requirements differ between markets, so the version supplied is matched to the destination at the point of order rather than afterwards.

How quickly can a repeat order of Vape Sourcing e-juice be dispatched?

In-stock repeat orders normally leave within 7 working days, and consolidated freight shortens the door-to-door time considerably on larger consignments. Planning the reorder point against the slowest leg rather than the fastest avoids the gaps that cost sales.
