Mini Aura is an innovative electronic cigarette. The innovation lies in three vexing concepts: 1. The ingenious top air intake and top e-liquid filling technology of Aura Mini makes the atomizer a bottom sealed, bottom non-detachable structure to avoid the leaking problem. 2. Aura Mini uses an innovative mouth piece design, by placing two tangent circuitous tunnels in it, so the e-liquid splash could be avoided by using the dislocation. 3. Aura Mini pioneers the use of two colors and light combination of different flicker frequency. Each malfunction corresponds to a certain light combination, so that every malfunction has its own clear light indicator.
