I ordered the 510 pass through from Altsmoke about 2 weeks ago. I just tried it for the first time today at work, since my co-worker isnt here today. For some reason, the thing doesnt seem to work at all. It doesnt power the atty at all. No vapor from the 510. I figured there are sure to be a few duds in the batch, and I think I got one. Just wondering what I need to do about this. On a side note, I love the 510 I bought form Altsmoke. The best e-cig I have!!!
