I always read one star and that's the only reason I give one star. The product deserves 5 stars. It's lightweight, easy to use, and does exactly what you need it to, which is to display footprint camera photos from an SD card in the field on your smartphone. To answer a few objections/complaints I've seen here... 1). Must be connected to the Internet, otherwise the application will not start. NOT CORRECT. You don't need an internet connection to run the app and read the SD card connected to the device. That works fine. You'll get an annoying little warning, but that's it.2). Doesn't read many SD cards. Not true. I tried it on three different SD cards from three different manufacturers, one of which was over 10 years old. Everything worked. I had an SD card that failed, but when I checked it on other devices, I found that it was defective. I have several SD cards that just broke in security cameras over the years. 3) The card must be smaller than 32 MB. Not true. I've used two different 32MB cards with no problems. I didn't try 64 because it's not recommended and my camera doesn't work with it either. The only annoying thing about this device is that you have to disconnect the device from your phone when you switch cards. Simply changing the card will not recognize the new card. Erasing pictures would be better if bulk erasing software allows full erase of card. Selecting individual images is tedious. This is great innovation and a good product.
