The card reader doesn't always want to switch on. When I first received it, it took several attempts to attach. Tried long and short key presses. After some trying, it finally started. It seems trickier at lower temperatures. The reader was left in my truck in the 30's. I've tried turning it on 50-60 times, it won't turn on. I found that what caused it not to turn on at first ultimately failed. The next day with a temp in the 50's I tried about 10 times and eventually it worked. The other thing I don't like is that "wiping all photos" actually reformats the SD card. When I put the SD card back into the camera for the first time, no pictures were taken and the wrong format was written on the screen I had to reformat the card with the camera to get it working again I am not impressed with this viewer and would not buy another nor recommend it.
