Hi guys, I have a cool fire iv and had it for couple of years but every juice I use if it's high nicotine or low is it's so strong I have tried so many different ones and even made my own with no nicotine and I just can't seem to enjoy it. I have used cheaper e cigs and it always tastes and feels really good but with the cool fire I can't I lower the watts and but everything's the same. I have the aspire tank. Can you guys please help.
