Quality / price ratio for a 64Gb SDXC Works great. Taiwan received live in 1 week. By cons 64GB card Attention arrives exFAT format that is not supported by Android tablets and Windows. Inserted in my tablet Lenovo impossible to run and unacknowledged, so no formatting !!!! Windows "Not formatted" and proposes default FAT formatting and what happens ..... after formatting the card capacity 1GB = bad for SD 64 Gb bought cheap but still . To cope card issued in a portable PC W7 reformatting demand exFAT we find our 64Gb then you have to go to a FAT32 formatting that it is recognized by Windows & Android .... But the problem is Windows does not know "native" format an SD 64Gb an exFAT format to FAT32. Only way to download a small utility "guiformat.exe" (Google is your friend !!!) the launch and format it with the SDXC 64GB card in FAT32 format. Then no problem we can put it into a tablet (eg Lenovo Yoga 2) Android is it's OK. Hoping that my experience can serve to computer side neophytes who would put this as soon unpacking card on a PC or a tablet ...... and could not believe it works, what does not cas.Elle works very well, it's just the starting size plant problematic.
