I like them, but the draw is so much easier (and yes louder) that when I threw on a regular carto it almost seemed broken and felt kinda hard to inhale. Never had that trouble before, now it is like switching cars, gonna take a few minutes to adapt from one to the other.
These 510 things definately rock, I am still vaping on the same one this morning, if it can get me through a better part of the day then all is gonna be really good.
