Can you please confirm whether or not you are supplying Pockex coils in white boxes? The reason I'm asking is I've ordered several boxes of "original" Aspire Pockex coils that have come in white boxes and around half the coils don't work. They either don't screw into the e-cig properly/at all or simply don't work when fitted. I believe the white boxed products are knock offs and only the ones in black boxes are original. Can you please confirm this for me as, if the white boxed ones ARE genuine, you have a serious manufacturing problem. Thanks in advance, Steve.
