this product does not work with my iPhone5s. yet, the seller insists to me that this should work. but at least with mine I tested, I iPhone5s officially purchased from France apple store, it does not work because this product has not been certified by Apple (displayed on the screen). Lightning is the problem. I read an article, now, the non-certified apple lightning cable does not. but what is worse is the seller. he insists that it works. and I returned this product directly to the seller Kelkoo. to the address of store marked on paper together in the product. but in fact, do not do that! you had to follow the procedure indicated by Amazon (amazon has offered to return the specific address for the return with the label) ... the result, the seller, they tell me they still have not received. and I can neither seek reimbursement or exchange, or recover article ... it is very strange because another package I sent to another address was well delivered. I'm not sure if this is really lost in the mail. I doubt if the seller did not seem to have received, not to make the refund .... well I can not know but in any case I will never buy from this seller is clear because they do not make efforts to address this issue and I have just lost money .. (the return shipping costs more)
