DV is a good vendor, fast service, and good prices on most items. One of the vendor I always check with, when I've found something I must have. They do have the best price on Kanger coil heads for sure. That's where I bought mine, when I was still using the PT. Was thinking on doing an SS mesh coil for the pt, but OMG, those are small azz wicks to wrap, how do you manage to wrap something that small? Have access to Nano robo-arms or something. lol. Ever since I received the Russian rba, the pt's have not been used, juice flavor to muted, vape production just adequate, it's hard to believe that they used to bring such joy to me. lol. I did give one PT to a friend at work, he was vaping on a 650 ego battery with a tank similar to an eVod. He started smoking again, something about stress, vape not doing it any more, lent him the PT original, with some Virginia Fired tobacco juice in it, and he's vaping again, without smoking. Asked him how it was going today, Said it was going good. Felt good helping a friend to get back on the vapping trail.
