The greater the resistance, the less smoke you have, the more flavor has one.
Despite 2.1 Ohm the smoke is still more than adequate and the liquids taste much more intensively. In fact, similar to a normal cigarette.
The lottery effect when the durability I can not confirm at present. My first 2,1Ohm evaporator I now have more than 6 weeks in use and it does not make long limp. I hope the other 4 are the same. The 1,6er were after 2 weeks or sometimes after 2 days by already. So apparently, the higher the resistance, the longer keeps the evaporator. :-)
