The cart may not have been dry
That's what I was thinking.
I usually always vape my cartos until I think they're dry . . . but last week I was refilling my Cola Premiums (Hard Cap) and I do what I normally do:
Drop 15 drops into the condom and push the carto in and 2 of the 6 or 7 I had didn't even take the 15 drops (which is not considered a lot) so obviously I was wrong about them being dry.
I'm told you get better at figuring out when you're cartos are dry as time goes by.
Just remember to push the carto down very slowly so you'll catch the first hint of juice and then you can stop and the suction generated by removing the condom makes the tiny drops of juice get sucked back into the carto.
Yes, I know what the condom, sucking and tiny drops of juice part sounds like
