Last night, I ordered Magic Bands for our 2020 trip. Okay. It is early. But, you know. It just makes us feel happy.
Posting photos of the choices for myself and my wife. (The kids, we just got the cheaper solid colored ones: Lavender for my DD, Navy for my DS9, and White for my DS16.)
I don’t think they can be changed, I’ve never heard that. But you only need the battery for long range stuff. Everything that you tap for will work indefinitely. And even the 2 years is a minimum, plenty of people have used older ones with no issues.
Sorry, I sorta just repeated part of your post. And also it’s important what you said about short vs long range. I think after the battery dies, the in-ride videos are the only thing you can’t get anymore ? For the in-ride photos, you can always tap at the exit (I think there might be exceptions to that though, it’s a little foggy).
