I ordered a couple of the rebuildable models, and I am a little disappointed with the wicking. They just don't seem to keep up with my vaping. I really loved the disposable ones though. Has anyone else had this problem? Or a possible solution? I'd really like to use them if there is a simple fix, but just can't handle the burnt taste on the third puff or so, and that was after letting the liquid soak in for a good long time.
