Would there be anything technically stopping me? I realize I did not need to register my device or provide a mac # as I used to have to do with my Mag 254.
Edit 1: Thanks for the responses every, I truly appreciate it. I will provide an update for confirmation. For anyone in my boots - I have 2x Amazon 4K firesticks (bedroom,living room) and using the app Perfect Player.
If you have 1 m3u connect you can use it on as many devices as you want just not at same time. You won't be banned if you use 2 devices at one time however one feed will cut out and/or buffer so using 2 won't be possible.
