For the price it's nickel! the 64GB micro SD card works perfectly in my new ASUS ZE551ML and I'm really happy. In addition to the USB key to adaptation to directly read the card on a PC works nickel. Well the only worry is that a Philips TV has not managed to read the USB key to watch a movie that was on the micro Sd. But as this was not the first goal of this card I do not care. In short a good choice for just over 30 ==> perfect
