Why is it that my passthrough has to be soaking wet (ie - liquid practically pouring into my mouth) to hit? I have tried it with different atomizers, and do not think the atomizer is the culprit. Is this normal? I can put a wet cart on my battery powered e-cig and vape away, but my manual has to be soaked. I feel like I am wasting my liquid, but I like the superior hits, (and lack of work) I get from my PT. Any suggestions?
