I really dont know how I would get by without this app these days. I have a monthly subscription, and I listen almost everyday on my phone. Have it on my tablet and the hand off is flawless. When I set the speed to x3 it feels like Im Neo from the Matrix downloading information straight to my brain. They tend to have trouble sometimes after an update. I have had problems with books disappearing from my library, and forgetting my place in a book, but they usually get it sorted out in a few days.
