Harsh does not always mean broken
A vape that feels too sharp is rarely a defective kit. Almost always it is one of a small handful of everyday settings that can be turned up or down by a notch. Nicotine strength, the kind of nicotine in the bottle, the ratio on the label, the airflow on the kit, how hard you draw, and the age of the pod all change how the pull lands. The fix is usually one small adjustment at a time, not a whole new device.
