4 stars: Sometimes the download speed is on the slow side, this wouldn't be an issue if comics could be downloaded in the background while I'm using other apps. Additionally, I wish the app home screen opened to my library instead of the shop. However, there is a great selection of comics showcased in an easy to read platform.
4 stars: Glitchy with downloads sometimes, doesn't do well if alot of time is spent searching without stopping and closing app. Wish more series would be fully available on unlimited. Shouldn't have to pay for ability to demo series before buying them. I pay to read and enjoy full stories and not first issue or volume.
4 stars: Love the comics, but the shopping experience is a mess... Also, there a weird bug in the app: regularly, especially on DC books, the pages will load and then be reduce to a single pixel line at the top... But it can be fixed in the settings by disabeling \
3 stars: Good features, great library, a few issues have pages imported upside down which is a solid reminder of Amazon's usual level of care and attention to detail (Bezos didn't become richest man in the world by caring about customer experience), but otherwise a liveable app.
4 stars: I primarily use the app on a Galaxy Tab A, which is obviously going to destroy something like a Fire Tablet, but it could be more powerful. The app works on it flawlessly, performance wise. The image quality is fantastic on the 10.2 inch screen, and the guided view is wonderful....
