I bought these cards for my daughter's fire tablets and my son's Android device. At first the three items did not recognize the SD card. But I let each device formatting the cards and it starts working fine.

This little card has a great write speed on it. I used this one in a Raspberry Pi where I had to regularly copy file to it over the network. It writes very fast, bursting between about 94MB/sec and 114MB/sec Compared to other cards I have tried which were in the 20MB/sec tops. For the price you just can't get this performance in any of the other brands I have tried.

Product arrived timely and works as advertised. I would have only went with a similar product/same brand however this one was discounted. Easy to install into mobile phone and makes a difference in overall phone ability meaning much greater movies, streaming, music, and work capability I recommend this product or the same brand but a better offering. -T
