It most likely not that the guys at Innovapor were intentionally misleading anyone. It's probably the case that Shenzen Jieshibao Technology is the ultimate culprit(since they are the , most likely, producers of the knockoff atty's). If you take a trip over to Innovapor's subforum right now, however, it seems they have alot of "unhappy" customers whose carts aren't fitting properly. I don't know, you really should be 100% sure of a part before you list it as a genuine product on your website. I was JUST about to buy 4 atomizers from them(so $40) and luckily I checked the forums before I hit the purchase link on paypal. Otherwise it would be $40 down the tubes or at least a pain in the A** return process.
That's where I disagree, I'm going to talk to David (eastmall) later tonight to see if he sells true 510s or not ;P
