These cartos have a thicker veneer on them. They fit tight in the cone and cut off the air flow.
tj99959, I have tried that little trick and it does work on some of them. However, I have had a few that I just couldn't get a paper clip to push thru. It felt like the little tube had moved and I was hitting metal at the bottom instead of going all the way through and coming out the other end. Thanks for the suggestion.
To tell you how well it works, the carto that I am vaping right now has been on my PT since July.
So what brand do you use carpedebass?
ooooops. dual coil..............
I've gotten all my Bogelr's, since March, from a reputable supplier- Vapor Kings. Not even one was bad, they last very long, and they OHM at 2.0 exactly.
