64 GB on a micro-SD card ... that itself was amazing to me and Sandisk has perfected the technology.No complains whatsoever, works great in my S4 ... have been clicking photos and videos ever since i put this in.It comes with an adapter, so you can plug it into your computer and download content easilyIts fast, even if it is almost full - unlike other cards i have used where it starts to get slow as disk space runs out ... not on this one, its fast. period.Few other reviews said it gets hot during operation, but honestly i did not notice anything .. not even getting warm.Also note that this is an SDXC card (different from SDHC), so please check if your device is compatible with it before buying it.
