I received a Magic Box today. I did not sign up on the first day. I waited a few weeks. I'm in north Boulder, CO in a lower elevation area and have horrible coverage, though there are a couple antennas not far from me.
After trying various windows, I only found two on my second floor that would connect at all. Magic Box reported them as quality level 1. Eventually, I chose the Use Anyway option. The Magic Box is now working and connected on Band 25. My DSL Reports speed test numbers are nothing to write home about, but better than without the Magic Box.
When they turn on VoLTE, or even Calling Plus for the iPhone, it will be a significant help.
I'm not sure how to embed images from imgur, but here's a link to my Relay and LTE status screens.
