After an unfortunate experience with a 128GB Sandisk microSD who planted on my mobile SONY XPERIA Z2 yet very recent, I was very happy to spend this TOSHIBA product that works very well. This micro SD 64GB offers high performance, copies of videos, MP3 music and photo albums are made at high speed. Micro card comes with Toshiba handy adapter. I can not recommend this highly reliable product.
