Double checked. Totally said joyetech and even the pictures on the website have the joyetech emblem on them. Nowhere on the page, after reading every small detail, does it say that there is custom branding on it.
Seen custom branding before and would have avoided this one had I known. The price was average, nothing spectacular.
I'm kind of in the battered wife situation right now... I love the twist and it's the only large battery I've owned. I need nothing else. Sending it back would be too hard. Just a little bummed.
Being as branding seems to be a big deal to you, I would suggest you contact any supplier you want to do business with then and ask if they use custom branding. Then you can simply avoid all who do.
