I bought for data to transfer the stick to my phone. Unfortunately this is not possible. My Samsung S3 is in a Love Mei envelope. The border to the USB port is so high that I can not get connected to the stick. For the stick can of course nichts.Deshalb there for even no star deduction. It exists for the data transfer. That's too slow for a SanDisk flash drive. I have another this company and transfer the data much faster. I have no programs to evaluate the, so I can not specify seconds values-hence no further details available. Otherwise, the particle is a good idea and will work with our trays fine. Both USB connectors are securely hidden behind a protective sliding device that locks itself and not pushing back during transport. Thus, not quite a bad buy, just use it in a different way and for that he is serving, slowly but finished him.
