Dear friends! We have an important announcement for you! Lately, we have received feedback that the use of other producers' liquids in our atomizers shortens their useful life. We recommend using Nicorex liquids - these are pure and all ingredients have the highest level of purity to prevent them from singing and blocking the atomizer, We can say the same about batteries. The voltage of other producers' batteries fluctuates - the voltage ranges from 4.2V for full battery to 3.3V for an almost completely discharged battery - therefore, these batteries shorten the useful life of Nicorex atomizers by subjecting them to an over-voltage of 0.5V.
