Help with iSub G tank

[X&Y]

Wondered if anyone had any advice.

Got a problem with one of my iSub G tanks.

When i MTL (never on DTL) most of the vapour is not coming up through the chimney part and is instead escaping out of the airflow airholes.

It's also only an intermittent problem and usually starts about 3 seconds into a pull.

Thanks.

Sometimes I get this too- It hasn't caused me any real problem though.
I put it down to my particular chugging style! that is to say not always just inhaling, more of a slight inadvertant in and out puff.

I think that vapour will definitely come through the airholes if you blow instead of just straight inhale.

I had quite a bit of vapour coming through the airflow slots on mine when I MTL, I've put the standard wide bore drip tip back on, slightly airier vape but I quite like that now, but it does seem to reduce the amount of vapour going through the airflow slots.
