Im using a samsung note 4..it has a micro SD slot on it and have changed out my SD cards in my cams to the micros. It works great and is 10x faster than the Ipad..the Ipad has to download every pic to it which takes forever if you have 3,000 pics to look at.
I bought a cordless electronic picture frame. I have a way bigger screen and paid less than what they want for a "game camera card reader"
