The iCare 110, a new starter kit by Eleaf, is 11mm in diameter with an inbuilt tank that has a leakproof bottom design. It is quite easy to use and convenient to carry because of its simple structure and tiny size. The e-liquid can easily be refilled by unscrewing the top cap. To power it on or off or to activate the tank can easily be done by simply holding the button. The iCare 110 also comes in a variety of colors to choose from.
