A:Answer Yes, works with Amazon, no, don't need monthly subscription services like Roku or stuff like that. It's simply a 'casting" device-as in anything you can view on your tablet/smartphone, you can send to your tv with this plugged in. (note: if you have a 'smart' tv, this capability is probably already built in, you just need to 'connect/pair" the devices.
This isn't a direct connection TO service providers (such as Netflix, Hulu or Amazon), nor can you record or anything else. it simply allows you to view content from your tablet or smartphone on a tv this is connected to. Think of it this way; it's really just a wireless way to turn your tv into a large monitor for your smart device (tablet/laptop/smartphone). Also, most major channels are now offering their channels independently (going with the public sick of rising cable costs) and stream a LOT of their shows directly.
