The iCare is a compact e-cigarette starter kit with an internal tank and airflow system. It is quite simple to use for the On/Off feature that initiates when vaping. The e-liquid can be refilled into the tank from top with ease. By using a higher strength e-liquid, the iCare perfectly recreates the sensation you are accustomed to. Also with intuitive three color LEDS, you can easily check the battery status by a simple glance at the color of the light.
