If you're EVER concerned about whether the retailer you want to buy from is indeed selling genuine Joye products...do what i did
go to
joyetech.com and email their customer service department with a link to the website.
By law they can not tell you who that retailer's distributor IS, however they can tell you whether or not they do indeed go through a joye distributor.
I didn't even think of the possibilities of knock-offs when i ordered my eGo...while it was in the mail i emailed
joyetech and got a response in like 1 or 2 days confirming that my retailer was legit. Hope this helps.
Edit- it could also be janty or totally wicked you're looking at...im not sure..but find out which of those companies it belongs to and email that company

sorry
joyetech was the example for the eGo i ordered..im not sure which company you're buying from.
