Well ive been vaping for over 6 years now & thought all nic was close to the same quality & thought how could it really effect my juice I make that much till I stumbled across vaportek's nic I heard some real good reviews. I was still a skeptic till I tryed vaportek's nic & let me tell u the quality of this stuff is amazing. I have some mixes ive been making for a long time & ive even cut down the % of flavoring I use, theres just no pepperish taist or anything for that matter to mask of the nic its so crystal clear n clean.. I was In shock! called up kevin the owner & he was nice helpful & I could tell he really really is all about quality. hats off to Kevin & his team they really have the best quality nic ive ever tryed. just had to share hope you all get to try it & injoy the nicotine as much as I have.
