Micro-sd card similar to the description on amazon fact, the only problem is that the supplied adapter is not working. After several exchanges with the seller, it told me it referred me another but I am still waiting. Alternatively, to return to the product itself, there is no problem. The transfer of data on the card is fast and it is compatible with my Archos tablet. Level quality / price, there is no better. Beware, if I 3 star rating is because the adapter is managed deteriorated me. But maybe you have more luck than me ?!
