i got my first e cig on monday (1100 mah enso axis battery and a 2 ml aspire tank). earlier today i accidentally got a little fluid down the air pipe. i took the e cig apart and carefully cleaned out all the parts to remove the fluid and then reassembled/filled the tank. my e cig ran smoothly again for about half an hour and then out of nowhere the cavity underneath my drip tip started filling with fluid and fluid would come into my mouth when i hit it. i took the tank apart again cleaned out the drip tip and blew any fluid out of the air pipe. it started working but the same problem occurred after about 10 hits. does anyone know what is causing this and if/how it can be fixed? thanks
