Finding your perfect setup is tough. I have been
vaping for almost two years, and have spent a boat load of money on gear. In my opinion the best vape is an Ikenvape 801 fusion carto in a J-tank from electronicstix.
As for the
juice not tasting the same, your taste buds are probably healing, which makes things that used to taste great taste like crap. I was in love with one particular juice early in my
vaping, I went through 120 ml a month. Then one day it tasted like crap. I could never vape it again.
Hang in there. Once you find the setup that works for you, stick with it. Good luck!
