I don't have time to rebuild due to a hectic work schedule & I have tried about every tank their is & I'm lead back to the good ol Tobeco SuperTank. It's the one tank I have never had trouble with. Now it comes with mesh coils, for anyone looking for a mild subohm tank, this is the tank to try. It's watts are between 15-30watts & it has great flavor & decent clouds for the wattage.
