A great solution if you want to go look at the pictures in digital camera with a mobile phone, and the phone supports USB On-the-Go (OTG) function. I have tested it with a Samsung S4, and it worked immediately. The unit is very compact. After I first experimented with Wifi-enabled SD card, but was not so happy for several reasons, and I think it is not nice when you have to handle with cables between mobile phone and camera, I have now found the ideal solution. SD card from the camera to take out, plug in this small adapter, plug the adapter card to the OTG-enabled mobile phone, and you can already see the pictures. I'm going to order me a second, so I'm sure always have a case.
