I loved these things in the beginning but now I'm moving on
I've found this happening on the connection end after a few days of screwing and unscrewing....it also doesn't help that they constantly go in and out of my pocket
it gets so bad that the tube will actually pull itself off, end up at some weird angle in my pocket and leak
but the absolute worst is the weird heat/air flow issues that develop...after a few incidents of tube slipping they do NOT draw the same...they get really hot, nearly burn my throat, refuse to draw correctly, the taste changes for the worse and it feels like it spits juice or something...
back to the chromies it is...I'm also gonna give the smoktech 3.5 mil tank a try too and see what's doin there
