Perfection starts with precision of design and development. The NX75 mod represents Aspires commitment to produce the pinnacle of vaping products. Refined lines and high-level design accents are apparent throughout the entire device. Intuitively designed for easy navigation through the menu, the NX75 Mod from Aspire allows the user to easily access his or her wattage mode or temperature modes for quick changes. The NX75 mod requires (1) 18650 battery (batteries sold separately) and is replaced through the magnetic battery panel to get you from 0 to 75 watts of power in a pinch. Different models are available with the chassis construed out of different materials which include the NX75-S (Stainless Steel) and the NX75-A (Aluminum).
