Im a newbie myself. I've been vaping for about two months but I'm not completely off analogs yet. Making progress which is great. I'm about 75% off analogs but keep a pack around for security when my devices fail me in some way.
One thing I wish I knew was the fact that 510 threads seem to becoming more or less the standard. I bought a Halo k808 set as my first rechargeable set. It's fine but I wish I had gone with something 510 instead. Every other device I have bought since (Ego, Vamo) can use 510. My Halos are kind of orphaned now. I still use them but can't put the cartos on the ego battery which would be nice since I do enjoy a carto vape.
My my progress was fairly normal, gas station disposables, rechargable cig-a-likes, Ego, Vamo.
