OK...just opened my last pack of 5 smoktech dual coil cartos...and not a one of them have side air holes above the threads of the connector. Discovered this after filling one and having my head collapse from trying to suck on the damn thing. I've never seen this before; anyone ever run across this? I'd send them back, but to be honest I don't even remember where I got them. What would be best -- drill a couple tiny holes in each one or try to punch them somehow?
