Very good product, however many devices do not read. SDXC is not very common. My Acer tablet does not read it. My SLR camera Pentax yes but I still reading problems later on some pictures !!!! CAUTION also adpateurs All USB / SDHC or SD / SDHC do not take into account !! Well I hope the software updates will be considered more stable this new SD format
No problem on computers to date to read
In conclusion I would say that it is too early to buy a SDXC. It is still expensive and few other compatibility that PC!
