The Oddy RBA Authentic clone is a quality built tank. It is made of stainless steel with a clear center window. In tank mode it can hold about 4ml of e-liquid. The Oddy can be used solely as a dripper with excellent sealing throughout or, by twisting the actual mouthpiece you can twist the e-liquid feed open to start feeding the wicks automatically while in tank mode. To use it in tank mode close the juice feed, fill the tank then adjust your e-liquid feed as needed. Please make sure you drip about 3-4 drops into the coil head to prime. When coiling your wicks leave a healthy inch to an inch and a half as the coils feed down the wick channel. The positive side goes to the stem and locks in the connector. The negative side does not have a post and instead, as you can see when you open your Oddy up, you hook the negative side and as you place the knurled ring on, it makes contact. If you are having or showing an open circuit this is the first place you should check and adjust.
Rebuildable atomizers are only for experienced vapers with access to multimeters and a working knowledge of how electronic devices work. Please ensure to take care so as not to cause damage/harm to the atomizer, vaping device, or yourself.
