How often you need change your wick depends on your vaping habits. The e-liquid that you use also play a role. As a rule of thumb, you might have to change the wick after vaping 50ml of e-liquid. You can typically change the cotton three or four times, before you also need to change the coil.
Keep in mind that this product is intended for experienced users. We strongly encourage you to build your coils on a regulated device. We would also like to remind you that if you use coils with a resistance below 1.0 ohm (Sub-Ohm), you need to use appropriate devices and batteries.
