i have been vaping since mid july, i use on average 10ml's a week, i started with golden virginia flavour as that's what i smoked in analog form, when that was finished i bought an evod BCC tank and another bottle of GV, the first day and my tank started gurgling and leaking fuid, i tried all sorts of fixes but after 6ml's in 2 days i took it back to the shop, they gave me a new tank and replaced my lost fluid with a new bottle and i decided to change to red bull, the following 6 bottles were all red bull as i loved it that much, after bottle 4 i started to go off it as the flavour wasn't the same as when i first used it, the shop suggested to buy a variety of flavours and change flavour each time the bottle is used, i got redbull, blueberry and honey bee, i've now used the blueberry up and before i started the honey bee i tried the red bull, sure enough it was like the first hit i'd had of the red bull, back to the same great taste, i'm currently using the honey bee and will use red bull when that's gone
for future vaping i'm going to buy 3 bottles at a time (cheaper offer in the shop) and stick with 1 red bull and 2 others, the beauty of the shop i use is they have 0mg nicotine testers so you can sample before purchase, i think if you can find a shop that allows the testing it saves wasting money on flavours you may not like
