Not A Good Choice if you want stable Playback, or if you have over 5,000 pictures/videos
I have 2 video files that have never completely finished uploading. Manual or automatic, these always show up in the queue and only eat up data and time.
Also, I had uploaded all of my pictures and home movies; then, the app crashed and I decided to reinstall it because it would continue to hang -- bad idea. You have to wait for all of the photos and videos to cache, which took over ten days to finally get access to the library on my phone. The more you upload the worse it will be if you ever have to reinstall the application.
These were nuances and caused personal annoyance more than anything else; otherwise, great job as always Amazon!
