On sparkplugforsmokers.com you can buy the thermo 6V tube extension for $11.99, the button end cap for $5.99, and the atomizer cap for $5.99. I emailed them to ask if anything besides batteries and an atomizer would be neccessary to vape and their answer was no. Now my question. Is this one of those you get what you pay for type scenarios or is this a solid mod at a good buy? I mean for $24.00 plus shipping I can get a 6V mod. Seems ................too good to be true.
