Smart, small streaming box that provides access to the online video library of Amazon and a few more vendors (eg library of "Das Erste"). The operation is very simple. Of course you need an Amazon account with Prime and Internet access (wireless or cable). I use them for my TV in the Home Office, the "Great" hangs a PS4 with the Amazon app. The operation is very similar to the PS4 App. If you already have a PS4 and can do without gimmicks such as cloud, smaller games, etc., Fire-TV does not need. Otherwise access, a good and uncomplicated product.
