Good product difficult interface – SanDisk iXpand™ Base Review

I like the product. Backs up my pictures and videos very quickly. However the navigation of the software is cumbersome. When I select a picture from the thumbnail views to see it larger, I can't figure out how to get back to the thumbnail views without killing the app and restarting. Very frustrating. Beyond that is decent.
