I'm trying the Kanger 0.8 ohm coils in a Kanger T3D with a Vision Spinner 2 at 3.2v. On average, how many ml of juice should I be able to go through before the coil is not usable anymore? Does the coils ohm and battery voltage make a big difference in the amount of juice used before a coil is beat? For example, if I used a 1.5 ohm coil at 4v, would I get more ml per coil? I do like the 0.8 ohm coils. The taste is great and I get a great amount of vapor.
