The Level X 15000 sits in the middle of the Boost pod range, a pre-filled Flavour Beast pod good for up to around 15,000 puffs depending on how you vape. It uses a dual coil setup for steady vapour and consistent flavour through the pod, and it has adjustable modes that boost the flavour when you want it, though the full boost feature needs a Level X Boost battery to work. It fits all Level X batteries otherwise. A couple of practical touches make it easy to live with: a soft anti-slip grip, and airflow you can change by twisting or flipping the pod, so you can set the draw tighter or airier. The nicotine is 20 mg/mL salt. Like the rest of the line, you keep the battery and replace only the pod, which keeps the cost and waste down over time.
