The Sumo 25mm RDA by Bruce Pro Innovations presents a well-balanced rebuildable system deploying a performance-oriented two-post, dual terminal design along with the integration of dual side airflow along with multi-directional intake top cap. Beautifully crafted within a 25mm diameter chassis, the Sumo RDA implements minimalistic lines consisting of precise engravings along the sleeve for a polished finish. The build deck deploys a user-friendly two-post, dual terminal design, with 2.5mm diameter terminal per post to accommodate a wide range of coil configurations. Coil leads are placed within the terminal openings, side-secured for user-friendly configuration while the positive post is gold-plated that increases consistent connection. Inside the chamber, the added mushroom-shaped center post, measuring 6mm by 3mm, is used for juice splitting that evenly distributes e-liquids to both sides of the coils during the dripping process. The central airflow channels enters the structure through a uniquely design dual airslots on each side of the sleeve, delivering a direct-to-coil effect and working in synergy with the multi-directional intake top cap. Uniquely built for performance with a plethora of ergonomic functionalities, the Sumo RDA by Bruce Pro Innovations is a truly dynamic rebuildable dripping atomizer.

Rebuildable atomizer: The user of this atomizer must install wick and wire (coil) in order to use it. This atomizer is not pre-installed with coil. Installation is required. Wick, wire and mesh sold separately.

Important Note:
Rebuildable atomizer coils and wicks have known risks.

Rebuildables are for experts, not average or beginner vapers with no multimeter or knowledge of how to use a meter, or when a meter must be used, or how electronic devices work. These materials cannot safely be used by the inexperienced or those without basic knowledge of electronics.

This is because:

1. A rebuildable coil/wick MUST be tested carefully with a meter before it is used.
2. If it is not tested it is entirely the risk of the user.
3. Faulty wicks/coils WILL blow electronic devices.
4. New coil/wick units must be tested and then used first on a strong basic electrical APV that has short circuit protection.
5. No new coil/wick assembly should be used on an electronic device until known to be safe.
6. These items destroy electronic devices if faulty. This is a known issue.

Due to the nature of this product there is no warranty. This product is for experienced users and requires technical knowledge in order to properly use it.

Nimbus 9 will not be held responsible or liable for any injury, damage, or defect, permanent or temporary that may be caused by the improper use of a LI-ION battery. Please have a basic understanding of the batteries you are using and how to care for them properly.
