I just received a new Vaperz Cloud vcp, aka piglet, and I tried it out yesterday and I couldn't get it to work. I put the batteries in a series configuration according to the markings on the battery cover, I tried different sets of batteries, which work in other mods. I tried a couple of different RTA/rda, which work on other mods. When I push the fire button, I get no response. I've emailed the vendor, but haven't yet heard back from them. Any suggestions?
