i have had my istick 30w for a month now and I'm rocking it with a kanger sub tank mini on it. I use the standard .5ohm atomizer with it and I noticed on the display its reading .6 instead of .5. I noticed this after I switched out atomizers because I kept getting a burnt taste and still getting a burnt after switching out a new one. I did everything proper loading the juice. I put 4 drop on the coil and the screwed on the tank and let it soak for 15 minutes. Can anyone help me with what might be going wrong. Thanks
