I just received my Joytech Egrip today and I can't get it to give me a hit. I've been charging it for two hours, I took the coil out and put it back in (as advised on youtube), but still when I push the button to take a draw, it just flashes a few times and appears to go dormant until I push the button again. It's very cold here lately, so I thought the cold probably drained the battery in transit and it's so dead I can't hit it while it's charging. Does anyone have suggestions, or verification that I just need to charge it overnight, or something? Or do I just need to send it back? I'd so appreciate any advice you'd love to sling my way! Thank you in advance! Moody Boo
