Does exactly what it says on the tin
I have a Sony Ericsson Xperia Neo, this memory card now allows me to download all the Apps and music I want onto my phone. I have inserted the card into the phone and it worked straight away without the need to format, I transfered Apps across with ease. The Apps I have tested so far work as quick on the card as on the phone. I highly recommend the Lexar 32GB Micro SD HC with Reader/ Class 10. I have not used the reader yet but I didn't buy this product for that feature as my phone connects to my computer via the USB.
NOTE: It is very important to check your phone/ tablet supports 32GB cards before purchasing as some don't.
