The Aspire CE5-S can hold around 1.8ml of e-liquid, the tank is makrolon with a stainless steel finish cover and two small windows so that you can see how much e-liquid is left. With the Aspire CE5-S you are also able to remove the drip tip / mouthpiece and replace with any custom 510 drip tip.
The Coils are replacable and are available under the heading, Replacement Coils. What you get: 1 x Aspire CE5 Stainless Steel Dual Bottom Coil Clearomizer
The Aspire CE5-S stainless steel bottom dual coil clearomizer looks very much like the Vision V3 but the technology is very different. The Aspire products use a dual coil atomizer at the bottom of the device which is enclosed in a metal casing. Compared to other bottom coil devices like the Kanger, the Aspires dual coils create twice the amount of vapour. The atomizer being at the bottom ensures that it is always fed with more e-liquid with each use, which means there is very little chance of the atomizer burning dry.
