My daughter and I got 3 of 5 set up. (Very excited to have them at the Colorado regional burn when we take the kids) No cell service. The night we got them she walked down the street. I drove my car in a different direction. Left the third one in a tiny library. Then I went and found her. And she got in the car and then we went and she found the one in the little library. It went flawlessly. If I get consistent using it, it will come in clutch when it's needed. Hoping it will be something that is just there, working and ready to go when and if it's needed and fade into the background when it's not. Start up and learning to use the device was pretty seamless. My 11 year old picked it up pretty quick too. I think there was some confusion around the color of the device. And which light in the gem belonged to which person/device early on. More clarity on that in the training video might be helpful. But I'm guessing it will become clear over time also. Also just want to say great work with the totem Tuesday emails. My partner is a marketing expert and I was so impressed by them. I showed them to her. They felt personable, informative, and following the technology you were building was genuinely interesting for me to read. I'm impressed. I hope you all do very well.
