IJOY Tornado Nano is the first tank offering a good balance between RTA and sub ohm tank system. Featuring the characteristics of RTA, it behaves better than normal rebuildable tanks. It offers a great second choice for vapors who enjoy massive cloud and RTA vapor system, which afford them a great taste, but do not feel like to DIY their own coil. It intends to offer the most convenient way to use an RTA tank. The novelty about the atomizer is that it comes with a color-changing glass tank. When it is exposed to sunlight or is used for a while, the glass will become translucent. What is more, the 18.6mm diameter build deck features 2mm diameter terminals, which makes it suitable for most coils. Besides, it comes with an innovative chip coil, which can provide the tank with a great cooling system. You can not miss it!
