i recently ordered one, and they are great. was working awesome until i noticed that when i hit the button no vape was coming out. i then noticed above the atomizer base isnt sitting flush on the tank. one side appears to have a slight gap in it.the other side touches the base and tank. i pushed it in a bit and that got it to vape but it still isnt flush and hasnt been vaping as well as the beginning. i dropped it once and had it in my pocket with my ego-c twist, not sure if thats what did it or not. i do have another atomizer head that i havent tried on to see if it sits flush, i hope it does and its not the tank itself. is there anything i can do to get the vapor back? thank you!
