It allows up to 4 family group users on basic
Uses your e-mail sign in not ip address
So you can log in and watch from any device any location
You can also pay more for unlimited family group users
My friend has 8 family members
I was in the original 4, new guys pay more
So it cost each about $60 bucks each for the year
You can be any where in the lower 48
Something to think about
