Yeah, I loaded the IPTV on both the FireStick and Firebox.
Actually, come to think of it, I loaded a media player on Fire stick&box and then linked the player to the IPTV service with my login info. Once it is set up, it works great. I only searched and saved a few channels from the IPTV within the player because that is all I needed: LHN, ESPN channels, Fox channels such as FOX News, and FOX sports channels, etc. $5 a month t is well worth it to me but I could see wifey and kiddies not liking the convenience of traditional point and click tv, OTOH, the technology is moving this direction anyway.
There are literally hundreds of sports channels on kodi add-on channels. You would have to go through those and save the ones you like or add more.
Edited to add: like several people have said, there several reasons to cut the cord but convenience is generally not one of them. In the free market, convenience comes at a premium... and it should.
