The device does not work with the appropriate app from the Amazon store with the Kindle Fire HD 7 but with the Kindle Fire HDX 7. On the Samsung Galaxy S4 and the g app from the Google Store Player function, the device also. Because of a malfunction with the Kindle Fire HDX I forgive only two stars. It should be possible to allow functionality with the Kindle Fire HDX within the elapsed time since the device and app purchased through Amazon.
