Hello! I'm so new and have been scouting around but just not hip to the codes and lingo yet. I have a NPRO and I'm going to buy some liquid to refill the cartridge because it doesn't last the day for me. I can see that is a common feeling. I'm assuming I drip the liquid into the cartridge itself that I remove from the atomizer and put it back on (2 to 3 drops right?), but I've seen some feedback about dripping the liquid on the atomizer. I realize this is a vaping 101 question so feel free to be sarcastic I can take it.
