The resistance of an electronic cigarette is an important consumable. Each resistor has an optimum operating power range. It is therefore necessary to choose your material according to the power so that the resistance of your clearomizer offers you a near-perfect vaping experience.
If you notice a drop in the production of steam or a less good rendering of flavors (burnt taste), then the resistance is worn and it must be changed. In general, always recommend the same models provided in the packaging of your kit or your clearomiser. But some resistors can be compatible with other clearomisers.
