The card reader recognizes to my surprise my 16GB 400x UDMA Transcent easily. Tested under Windows XP, Android and on my Nokia 808 with Symbian Belle (USB OTG adapter). However my Nokia bleats when inserting the card into a card error, but which is possibly due to the formatted with the MagicLantern firmware card.
Photos are displayed but any problems and can be copied via radio data transmission in the dropbox. Ideal for photographers who need to send their photos on the wild. The adapter has a power consumption of only 100 mA and is dashalb especially for smartphones.
