I am very disappointed with this purchase and I recommend this seller (45 for a memory card that does not work). Indeed this memory card has temporarily accepted the downloaded music and photos I took with my smartphone and some time after use, no trace of these audio files and photos on my mobile I tested also with another card memory and works perfectly. So I contacted the seller who told me to return the product: for sending the product the seller says he has received nothing so I will be not refunded despite reporting very early (before the end of 3 Recommended weeks) the seller of the non-conformity. Total rip off !!!!
