This is a very common question with the complex answers. With vaping many things like taste for instance are subjective and what works best for one person might not work as well with the next. Make the decision yourself and know what direction to move in if you are ready to move to a more advanced device.For beginners, we suggest low output regulated devices that use integrated internal batteries. Paired with Clearomizers that use easily replaceable coils with a resistance over 1.0 ohms.For intermediate, try a greater vapor or flavor production mid powered regulated devices (80w or less) and clearomizers with replaceable coils with a resistance at or above .5 ohms.For advanced, we suggest a high power regulated mod and a high wattage sub-ohm clearomizer.
