Thing is with so many variables involving vaping, HV LV %VG %PG flavors low V with LR atties/carto's etc, I'm afraid most people will give up before doing His/Her research and knowing there's a sweet spot for everyone... what brought me to do my research and end up in this site was exactly one of those radio advertisment, after 2/3 days reading here I decide to go with what most people consider a safe bet for starters and bought a Ego, I followed the veterans advice and got extra atties/carto's/juice etc when my order arrived I was ready to quit analogs but to my disapointment everything tasted awfull and I almost gave up on vaping entirely, but decided to come back here and find out what was wrong since so many people were happy with their experience, after more research I found it turn out the 3 tobacco flavors that came with the order gives me the headache and I also burnt the LR atties wick also carto's are not for me, placed another order for DIY stuff and found that I quite enjoy half of the flavors I prep, so it's all about due dilligence and trial and error. Sad thing is that untill a big company steps up to take the lead, lots of people will fall prey of misleading companies and never know what They're missing.
