What method do you use to test your ejuice? If you use a dripper, which ones are the best and where can you get the best price and selection on them? What kind of equipment and do you need an adapter? I have been testing in carts but I don't think they are giving me an accurate taste test on my equipment. I use a Coolfire IV with iSub G tank and Eleaf iStick 40W with a Nautilus tank.
