On another thread, I made an observation that the batteries from Eastmall is indeed different as are their atty's. And unlinke some of the members here, I don't like, nor use the new atty's (4 I got from them) and am going to phase out their batts (4 from them). I'm too lazy to send it back to China, so I have to chalk it up as a loss. If I knew prior that these were not JOYE products, I would not have bought it from them. In other words, I got duped for almost $100 bucks because of false and misleading advertising for a knock-off product. Never dealt with IV, but I am sure that is the same case for someone else.
Whether or not the knock-offs work the same/better is beside the point. Perhaps IV got duped by Eastmall as well, but now they know. And for them not to address this is just the whole point. I support Surf 100% in his reasoning!
Are those the new style with the metal plate/ring inside? If your willing to ship (i'm in California too, San Francisco) i'll take those off your hands.
