Use with Nikon D3100

With an SLR camera SD card, this is a more than a bonus really useful. Since the photos times like to have more than 8MB need the SD card a long time to transfer it to your tablet. That will be no joy, therefore all the pictures you draw best on Tablet and looks at it. The Shoot & View option I find very convenient because you just do not recognize on the small screen of the camera whether an image has become sharp or not. Clear need the image also his time and is first displayed pixelated. But better you wait 10 seconds as you come home until it all the images can in the trash;.)
The D3100 is a little, how shall I say, awkward. The Wi-Fi is only active when the screen is on. In other words, you have to each image such as on info so do not press the connection breaks. With the right settings that goes but then very easily.
I would buy it again, even if the price is a little high compared to normal SD cards
