This questions may have been answered and I just missed it. For those of you who use (you did not have to have made the mod) a modified E-Vaporizer and have also used a Screwdriver, I would like to see a comparison, such as Madogs' mod to the screwdriver. Specifically how does the the mod you use compare to the screwdriver in "throat hit", battery life, easy of use, reliability and time to re-charge the battery. Use a scale of 1-10 or just make comments. 
PS: I may also post this in the general discussion section.
