This is NOT, as I had assumed, a portable frame - i.e. it doesn't contain a battery but only works when plugged into the mains or a computer - so there is little point in buying one so small. It has a limited memory - I could only load 18 JPGs. The SD card slot works okay but the card sticks out at the side. It uses a random selection of slide transition effects over hich the user has no control. The "manual" doesn't even mention how to use the associated software (you can't just copy files over as with a drive), which is not itself intuitive.
