Summary: I own several digital frames, and have used more that I've set up for family. The ViewSonic VFA710w-50 7-Inch Digital Photo Frame is by far the worst digital frame I have ever used. In fact, it is so bad that I had serious reservations about purchasing another ViewSonic digital frame. I will say up front that I did finally take a chance on the ViewSonic VFD1028W-11 10.1-Inch Digital Photo Frame Features High Resolution 1024x600 (Black) and have been pleased with it.
Summary: I bought two frames, one for me and one to give a gift to my parents for Christmas. We are delighted with them, work great with SD card and USB memory. My parents are very happy with the gift. It is easy to operate. I recommend it.
Summary: This frame is really easy to use with an SD card but the image quality is somewhat low. But considering the price it's definitely worth it. Some images are randomly turned sideways, even after I make sure the file is turned correctly - not sure if there's a way to fix that. I would probably spend the extra money for a higher quality frame in the future, but I don't regret this purchase.
