That is just a listing on alibaba trying to capitalize off the A-mod / wotofo brand, same thing codevape is doing. At one point codevape listed the product correctly on their ebay page as an iJoye, but had it listed incorrectly on their website, then some redneck on youtube called it A-mod, and they went with it, changed it to A-mod on ebay as well.
Until I see a kayfun4 clone in an a-mod box with an authenticity sticker that checks out on the a-mod site, I will continue to believe people are selling random clones trying to use the a-mod branding.
I'm not disagreeing, just saying why folks think there are some.
