I'd like to add my two cents worth for Klasy and Sheryl...
Vaping does take a little getting used to. For many it's not an immediate transition as there is a learning curve assocaited with each type of PV you decide to use. Analogs get many people through their frustration of finding their "sweet spot" with devices, voltages, juices, etc. I say that when you are ready to give up the analogs completely then you will do so. It's not something that everyone can do; go out and buy their first or second PV and expect to be off of the tobaccy's for good. It took me some time as well.
I started with a blu at the beginning of this year, then went to a sidesho, then to a tornado, then to a box mod, then to a silver bullet. I've finally found my "sweet spot" with 6v vaping and the right equipment all around. One of my biggest peeves was filling carts...Like many I couldn't get a good filler and my stuff leaked like a sive. I finally took a shot at cartomizers (510) and have never had an issue since. I've also never touched an analog since because my flavors finally fell into line, voltage was exactly what I needed for that craving, and got a crazy vapor / throat hit.
If more is what you are looking for in a PV, might I suggest going to a higher voltage mod that will allow you to go 6v or 3.7v? That way it's cheaper to try / test atty's and or cartomizers than it would be to keep buying PV's till you get that right one. The Chuck, Xhaler from Nhaler, V3 from Puresmoker, or Silver Bullet from Altsmoke would be my suggestions.
Good luck to both of you...the support is here if you need it!
