Durable Plastic Tanks: Utilize advanced polycarbonate or PEI plastic materials for the tank section instead of glass. These are virtually unbreakable from drops, making them ideal for clumsy users or active lifestyles. However, some plastics can be susceptible to cracking from certain "tank cracker" e-liquids (e.g., strong citrus, cinnamon).

Water-Resistant/Shockproof Mods: Built to military standards (e.g., IP67) to withstand harsh conditions. They are sealed against water and dust and built with durable materials to resist damage from drops and impacts. Targeted at construction workers, outdoor enthusiasts, and users in demanding environments.

Glass Bell Tanks: The classic tank design where the main chamber is a clear glass tube. This allows users to easily monitor e-liquid levels. The glass is resistant to flavor staining but is vulnerable to breaking if dropped, so they often come with replacement glass sections.

Beverage Flavors: Designed to replicate the taste of popular drinks, including colas, lemonades, cocktails (e.g., Pina Colada, Mojito), coffees, and energy drinks. The challenge is balancing sweetness, fizz/carbonation notes, and acidity accurately.

Open System Replacement Coils: The core consumable within a refillable pod. These are small, self-contained units that house the coil wire and wicking material. They are replaceable, allowing users to keep the pod shell and just change the coil when flavor diminishes (e.g., Mesh 0.6ohm, Regular 1.2ohm).
