I bought one of these (Black frame) for my Mum for Xmas. Initial imression was that it was easy to set up, i.e. pop the photos on an SD card, plug it in and away you go. The initial impression of the picture quality close up isn't fantastic but from a bit of a distance is absolutely fine.
The one major drawback that I can see is that I transferred about 1000 photos onto the card and each time you turn the frame on it starts from the beginning again. A random function would help but I haven't found it yet if it does exist.
Altogether though you can't really complain for the price though, a great buy!
