I bought a 510 PCC kit , not a noob, just thought maybe after almost 2 years of vaping, these companies have maybe shored up the small batteries in these things. I was wrong, dead wrong, I have been using this pcc kit for 4 days, just last night one of the batteries died, blinking led, yet when I put it in the pcc it says its fully charged. So I open up a ticket for that battery, wake up this morning, take out the 2nd battery in the pcc charger, and screw it on the atty, no blinking led this time, just very short battery life, like maybe 5 minutes. So now I have a pcc kit with two dud batteries after 4 days. It worked great for those 4 days, that I was happy with it . I don't mind changing ecig batteries every 2 hours while vaping, but they have to last at least a month to be worth the price don't ya think? Anyways, here is to hoping they will take it back, if not I'm stuck with a pos pcc with no batteries to charge in it, no way I am going to keep buying these batteries just trying to find a few that will survive longer than a week.
