This thing is slick. You simply put the SD card in and see what's on it. For years I've carried an old digital camera. The pictures were small and very pixelated. I would hike into a spot to check a camera, swap a card and find out at home there hadn't been a single thing at that location. Now I can see what's on the card and either leave the camera or move it to a better spot. I like how big the screen is, how good the image is and how simple it is to use. Every one that uses it says I've got to get one of those!
