POSITIVE: easy to use, takes as input device EITHER the memory card from your camera OR a thumb drive (these are what I use with ease) OR can connect to some other device (which I do not have so cannot address). There is a time delay for the amount of time I wish to display the PIX for viewing and observing. AND this is a GREAT advertising gimmic for product or event display as people come by. NEGATIVE: I was hoping for a larger screen (which my next one will be). The device does "trim" the PIX just a bit. But for the price and the convenience and the ease of use, I definitely have been recommending this to those who see it on my desk.
