You can use one Amazon account to sign in on multiple Fire TV Stick devices, instead of needing to create multiple Amazon accounts. It is very convenient. I'm personally happy with my device. I've recently started using a USTVGo service and can watch all my favorite TV channels again. And it has to be noted, it is hassle-free, there is no need to install any app, just access the website on Firestick and start watching TV.
