Lets see where to begin. First and foremost I have tried many of the usual suspects when it comes to flavorings--Flavour Art, Flavorwest, TPA, Capella's and a couple Hangsen. I have some must haves in most of these brands but had many more that I didn't like. This has made DIY frustrating and very much a trial-and-error-and-spend-lots-of money-and-sometimes-be-disappointed process. When I first heard about the new super concentrated flavorings by Vaping Zone I was as usual for me somewhat skeptical. I am almost ashamed to say that now...LOL I have tried about 18 of the currently listed 62 flavors and counting this company offers with more on the way to me as I type this. The beauty of these flavorings is I no longer have to add high percentages or wait weeks on end or scribble down endless calculations to get a fantastic easy vape. For a high PG vaper like myself, the recommended 2.5% is plenty with some being better for me at 1-2%. This makes a $6.99 bottle of flavoring an incredible value in the long run. I consider myself a very particular vaper. I don't like vaping perfumes or having them in my vicinity as I am sensitive to perfume. Of the 18 flavors I have tried so far, none were bad and 15 are ones I intend to use again and again. For me, thats a borderline miracle as a fussy vaper. I don't blow smoke-- if I don't like something I will say so. Recently I have begun combining the flavors together with great results. Any of the fruits work well with the tobacco and cigar flavors. I have not received VZ's caramel or vanilla yet (both on the way) and used another company's caramel with VZ flavors and it worked out great. I recommend aiming for 3% total if you are using all VZ flavorings combos to start and you vape high PG. You can always add more if you need to. At this point, I prefer to stick with like minded flavorings that require low flavor percentages so I used FlavourArt Caramel and added it to my favorite Vaping Zone tobacco flavor- Black N Mild along with VZ's chocolate. I steeped it overnight and awoke to my husband vaping it. After I pried the bottle out of his hands I am happy to report its fantastic. RY4-ish cigar anyone? I'd like to say these flavorings are also superb as standalones too and my cartomizers are lasting longer. I highly recommend you try them. My husband and I have been amazed how much we like the tobaccos after trying so many so-so's or downright duds. Even if you don't like tobaccos-- I suggest everyone try at least the Black & Mild and see if your mind can't be changed. All the non-tobacco flavors are excellent too I haven't disliked one yet. Thanks for reading my novel.
