Mik at Janty invented the eGo with the cone, the original eGo. Janty Mik created it, Joye manufactures it. There are legitimate eGo's out there by different vendors now, but Janty still holds the best guarantee/warrantee that I know of. (it's been a long time since purchasing or researching, I'm probably outdating myself lol). The Joye eGo's are sold by many vendors with just as many "logos".
Then there are the "clones". They're not made by Joye, they are made entirely by different companies. Some are actually quite okay. (Riva for instance). Some are not so okay. (tinny, falls apart, thin, short life, bad threads, just overall bad product).
A purchaser really has to do their homework nowadays. It's not easy. I recommend buying your very first from the company themself ... Janty... because well, you KNOW it's original and you KNOW it has a warranty and you KNOW you can rest assured you can leisurly vape for a good 6 months while doing your backup kit research. Your Joye research. Your clone research. That's just to make it easier. I know there are lists of qualified downright righteous classic eGo vendors out there... but I don't have it on me and Janty is the only one that I do KNOW and fully trust (to date). (but there really are lots of honest Joye vendors out there. List!! we need list!!!)
I also like buying my Cisco's from Cisco, my Reo's from Reo's (or a close friend of Robs)... my Silver Bullet from Altsmoke ... my Boba's Bounty from AveJuice ....
