Great device to view photos already on the way more accurately!

Use the unit mostly on my iPad mini Retina, and so far only with a SanDisk Ultra SDHC Card 1 (40MB / s) with 32GB. What can I say? Card in, connect device to iPhone, wait until opens the Photos app, and then select the lower right "Import". Already you can all photos, or only selected images to import - and I mean really ratzfatz! And the app will detect and highlight even which of the images already on the iPad, so you as always has an overview. But it seems to be advisable to stay away from the iPad during import; For me, it has happened that passed with all the images after importing the bottom left a few lines only green pixels. Have the images deleted from the iPad and imported again, and this time the images were ok. Also you should watch what you tap if after import from the Photo app automatically comes the question of whether you want to delete or keep now all images on the card. One more reason not to do anything until the end of the import to the device.
