Each time I pat myself on the back as finally being a 'real grown up vaper' I learn something new ... Just discovered something that can be so subtle it can drive a vaper crazy. After expensive clearos are purchased, it's easy to start choosing favorite collers and thread covers for large pen styles ... it's easy not to notice that adjustable ventilation clearos always have solid filler collers underneath the adjustable vent holes ... to slip a better looking coller you might have from your battery collection ,you might not notice it also has from 2 to 4 holes all the way around that coller .... ya, you guessed it .. I was trying to vape with a 6 hole ventilation system and could not get a new premium clearo to even begin to work properly . While I doubt anyone could be sillier than I, I include this just as a reminder to any other newbie ...
