When you pick up a fresh device—whether it's a VERTEX-VISTA or a LINQ-SLIM—take a minute to check the airflow and the mouthpiece. Give it a gentle shake to make sure the e-liquid is evenly distributed, especially if it's been sitting in a store for a while. If it's rechargeable, give it a full charge before your first use. That first draw should be smooth, not dry.

And here's a trick: don't chain-vape right out of the gate. Give the wick a few seconds to soak up more juice between puffs. It's a small thing, but it makes a difference in flavor and longevity.
