Amazon.com Inc. (NASDAQ: AMZN) says it believes oops happens with kids, particularly when it comes to electronic devices, so the retailer is offering a two-year, worry-free guarantee that includes coverage for anything that happens to its Fire Tablet.

Seattle-based Amazon says in its advertising materials that if the device is broken, the company will replace it, with no questions asked. That includes electrical and mechanical breakdowns.

Amazon is trying to rekindle interest in its e-books at a time when sales of the devices are waning. U.S. e-book sales fell by 18.7% in the first nine months of 2016, according to the Association of American Publishers. According to the Pew Research Center, 65% of Americans reported reading a printed book in the past year, compared with 28% who read an e-book.

Amazon’s Fire 7 Kids Edition tablet starts at $99. The age range for the device is three years old and up. It has 16 gigabytes (GB) and is expandable to 256 GB. The device has a seven-inch screen and a quad-core 1.3 GHz processor and has dual-band Wi-Fi connectivity. It takes six hours to charge and has capacity for eight hours of reading, surfing the web, watching videos or listening to music. The device has a mono speaker and built-in microphone. The black tablet comes with a choice of blue, pink or yellow kid-proof case. The tablet offers access to 15,000 kid-friendly books, videos, educational apps and games.
