At first I bought the Vapor Vapes Flavorless juice to use as just a base mix. And it is stellar. A total winner - smooth, easy on the coils and just such quality. Also it is REALLY cheap and they stock it in up to 1000ml so I buy big and keep myself stocked up. I decided to vape it as is and you know what... it is the best. It's a pure and fresh vape and it has no scent (so bonus when you are trying to have the smell go unnoticed). I would say it is flavorless but it actually has a very light sweet taste, very slight but you can pick it up on the exhale. I can't say enough good things about this.
*Worth mentioning to the DIYers that want to keep it simple, buy the one with nic and just mix it with a concentrate. Cuts the time and effort in half and tastes the same.
