I am set and not looking to add any other device. I don't have a clue about the KODI add-ons. Originally I downloaded the software online but couldn't make heads or tails how to install it. So on my last trip to SF my son gave me a USB flash drive with everything already installed and step-by-step instructions on how to navigate the program. Works like charm,,,and it's free! Prior to that I had compiled on my own an extensive list of free websites where I can also watch series/films produced in many countries and available with English and Spanish subtitles. I continue to use those websites from time to time.
