It is hard when you start to go with a pv that DOES NOT look like a cigarette. If I did this I would have saved tons of time and money, but I admit I fell into that trap and it is a trap. The real danger is that those cig looking pv's turn you back to analogs. Hindsight being golden, I wish had started with a Reo (mini or Grand) with Boge 2.0 cartos then worked into atties when I got more experiece. After 9 months of experimentation I now have all the hardware and juices that are my favorites down pat. Most important NO CIGS for 9 months and counting. Good Luck.
I fell into that same trap...also spent tons of money. I think one of the reasons I fell into the trap was it was that this particular PV was the only one I could understand. The cartomizers were prefilled and it only had 2 pieces. Plus they advertised one cartomizer was equal to a pack of analogs. When the actual vaping experience was not satisfying, I turned to this forum.
