These are cartos from electronicstix, the ones that are laser drilled. I had this carto in my VPX
tank with no issues. I put it into the lavatank and after about 10 vapes, it starts to get into the mouth from the tip. Take the tip off, wipe any condensation off, put it back on and about 10 vapes later, the same. I took the same carto out and put it back into the VPX
tank and no issues. Been
vaping all day on it. The tip is pushed down as far as it can so it will not go down any further. I do not get leakage from the punch and the laser drilled have been spot on ever since I have been using them from Vapercon.
So no one has ever used an O-ring even for the hell of it? Just trying to figure it out as I love the weight, feel and look of the Lavatank I got. Nice dark blue swirl with a mixture of white and black swirls(mind tip).
