First let me start off by saying hello. I am new to ECF. I have been a member of another forum for over 3 years, but really liked what I saw here, so here I am. Sorry if this is posted in an incorrect place but it doesn't look like I can post as of now in topic related areas. When I started vaping, all there really was were pre filled cartos and atomizers. I have used a lot of 510 attys in my day. I since went away from them and have been using clearo's and tanks. Years later I figured I would get some more attys for juice taste testing. I just received an order today from LiteCigUSA of 3 510 "premium Joye atomizers" as stated on my receipt. I put one on at 3.7v and nothing. I tried the 2nd and then the 3rd again nothing. I have tried them on two different devices. I have many fresh batteries. All my other equipment is working fine on the devices. Is it possible these all arrived DOA. It really seems unlikely but I have no answers. On a side note, years back when I used atomizers, I used them on these exact 2 devices and they always worked great. I am at a loss.
