What good is it to RTA and RDA users. The idea is for folks who can't be arsed to learn how to coil and wick. I have seen folks moaning a lot to Driphacks about this "my coils only last a few days".
Yes you can blame the manufacturer but the truth is you have choice whether to keepusing that eliquid and put up with the coils lasting less or you can find another juice.
There is good liquid and there's bad. But Premium eliquid is marketing spiel the same as High end, all they mean is Fucking expensively priced. But no manufacturer is going to say that. Plus premium means lots of sweetner which is what fucks up the coils
You have another choice don't be so idle and make your own juice. You cannot blame anyone else then. So No there is no need for such info. on bottles.
