We occasionally ride with two octogenarians on Spyders who decided they need PackTalks. Our rides are normally short rides for lunch at a local cafe. Both are challenged by technology and I am certain will find using the PackTalks difficult. We go for our first ride with all four of us connected today. Should be entertaining…. Pray for us.
IMO, you need to set them up sitting in your livingroom in air conditioning, relaxing. The first time my wife and I went for a ride went spent two hours messing with them, after I thought they were set up! We gave up and had intercom, but notice we wanted, or maybe expected! If the four of you just want to talk over one channel it will be relatively easy. Add streaming music from your phone and it adds a bit. Try to run two different groups so you can have private conversations with your wife or buddy only, good luck, I'm not there yet!
Packtalks are not for the technology inept!
