The Vandy Vape Requiem RTA is a rebuildable tank atomizer designed for use with advanced vapers who prefer to build their own coils. It features a 22mm diameter base and a 2ml e-liquid capacity. The Requiem RTA features a single-coil build deck with a simple two-post design, making it easy to install coils and position wicks. The build deck is relatively small, so it is best suited for smaller or simpler coils. The airflow system on the RTA is fully adjustable, with six different airflow holes on the side of the tank that can be adjusted to your preference. This allows for a smooth, flavorful draw with plenty of vapor production. Overall, the Vandy Vape Requiem RTA is a simple and straightforward atomizer that is suitable for experienced vapers who prefer a single-coil setup and a restricted direct-to-lung vaping experience.
