Review on 4-in-1 Trail Game Camera Card Viewer - SD/ Micro SD Card Reader Adapter with 3.0 USB OTG Cable for iPhone/iPad - Easy Plug and Play Compatibility by Lawrence Reuter

So glad I have it! Instead of taking the SD card out of your camera, plug it into your computer, transfer it to your computer, email photos to yourself, open your email, and save them to your iPhone. . . All I have to do is plug the adapter into my phone and insert the SD card. From there I go to the photos on my phone, import and that's it! I share lots of wildlife and sunset photos with my sisters and they love receiving them. Now I can easily send photos and videos from my Nikon. The price is great!
