Summary: It has no internal memory but uses a usb flash drive which is a plus. It allows unlimited pictures. The downside is that the screen is not very bright and best suitable in the dark, not under office lighting.
Summary: We like the constant changing display of pictures and the ability to see them several different ways. And it uses 12 volts so we can use it in the motor home without running the generator. What we don't like is there is no on off switch.
