i just got this ego tank with air control and im a little puzzled....i assume u take the bottom cap off were the 510 connection is and thats were u fill it since it seems thats the only way to get the joose into the tank were u can cc it thru the windo it does not come out or leak so im pretty sure it goes thru the bottom...next question is wen i got it it came in a lil box..wen i opened the box it had a very long piece that screws over the top over the drop tip looks like a stylaphone at the tip of it(not sure what thats for) so i took that off and screwed on the air control and noticed under the drip tip is a lil bit of cotton but when looking at it no joose would be able to get to it..i understand it says not for beginers and im not a beginner but this has me stumped...is it just silica in side of it?am i filling it right?is that all i do is fill from the bottom screw it back on and vape?if anyone has got one of these and can help that wuld be great thanks
