love this forum and all you guys that help everyone so much!!! My question is i just got my joy ego. I am using it as it comes. With standard cartrige and 650 battery. Battery life is excellent. My question is after i fill the cartridge, It seems like i can only vape it about 10 times before i start getting that burnt taste in the back of my throat. I go to add juice and it will only take about 3-4 drops. Then 10 more vapes and i have to refill again. Is this normal with thes little cartriges? I hate having to refill every 15 minutes especially at work. Are cartos better in that they last a lot longer? Do i need to put more filling in the cartridge so it holds more juice? thanks for all your replys in advance!!!
