I'm not sure where the problem is, but I noticed with my new bottle of HS Premium Menthol Sensation, that a carto lasts for about 5 puffs, thats it. Burns right after that. It kinda seems like the e-liquid isnt soaking into the filler or something. Is this normal for certain liquids and what should I do about this? This also happened with my Vanilla from Freedom Smoke USA.
