I have 8 Joye Ego C upgrade passthroughs (650 and 1000mah) in rotation right now. Six of those I've been using since October 2012. I also use the Joyce CCs, EVODs, T3s minis and iSmoka minis as well as Smok AROs as well as the Joye Eroll (three full kits and an additional 12 batteries) that I'm equally happy with. I have multiple backup Joye C upgrade regular and passthrough batteries and dozens of the mentioned clearos and Type A attys in backup. That should pretty well tell how confident I am in these products. The only product I've ever been burned by was a SMOK L Rider Corola and that was by the Smoktek store. Its unfair to lump all members of a group together while ignoring individual differences: That's called "prejudice" and "discrimination." There are good and bad companies in every country. As for being treated badly, that's... sorry, your own fault... "fool me once......" kind of thing. I'll never do business with Smoktek again for instance. I will continue buying SMOK ARO clearos and probably buy one of their pyrex tanks to try. To steer "noobs" away from reputable companies and products based on prejudice is irresponsible to say the least. Joye batteries are some of the most user-friendly, safe and dependable ones out there for entry prices. If you can't overcome your prejudice, then go to the original innovator.... Ovale (Italian I believe).... but they're made by Joye. Your bad experience... sorry to hear it.... is not as much with the producer of the product as it is the vendor you chose to deal with. They're profit margin is not as narrow as they would have you believe. They could have made things right.
Edit: JFYI, I have seldom read a post here that disturbed me quite so much but then most prejudice does. My advice is to backup, chill and do some serious thinking about where hour head's at. And, btw, I also vape a few select Dekang and Hangsen juices without any concerns... and I'm not Chinese.
