Endless listening to all of the audiobooks you could ever want to find. Save time trying to find your book elsewhere and just signup, that’s what I did. I also love the free stuff and daily deals. It’s become a part of my morning routine to check what audiobook is on sale today. The app runs perfectly on my iPhone. I honestly don’t have any bad things to say. Considering how much I pay for my paperbacks and hardbacks I know I’m getting a great price too. PS I know I sound like a bot, but this is an unpaid & honest review.
