I made the mistake just once, of buying a large bottle (100mL) of an eliquid that I'd never tried...based upon really good reviews posted. Never should have done it! Was able to save it though, after steeping time and then by blending it with some eliquid and flavoring I already had.
My advice, especially to a new vaper, is to buy some sampler packs of like 5mL bottles in a variety of flavors to try. They're inexpensive and many vendors have them online. If 1 or 2 of those are ones you really like, then order a larger quantity of those.
Better yet, go to a local vape shop and taste test a bunch of theirs. Like one or 2 there...bingo! Would've cost you nothing but your time to find them.
