5 stars: Just got our devices. Love it so far. It works. Will see how we like it when it gets put to the test. --> Tested this in our area. No connection greater than 1 mile. My husband predicted this due to the valley we're in and other buildings and things that can interfere. Will test in other environments such as Six Flags Great Escape (No Project Fi Cell Service). Beartooth devices will be good for battery banks.
5 stars: Voice and text off grid works great. The down loaded maps are really cool. One issue with the map is you have to down load the street style and whatever map you want. With out the street it will not work once you are off grid. You can use a very large scale on the street map, like a whole state. But over all the off grid functionality is awesome.
3 stars: Wow this app is soooooo great... Could not get maps to work even after downloading them in an off mountain area with service. Using GPS currently only shows where your dot is compared to the other unit... Zero scale for distance, just a blackish screen with my Dot and the other units Beartooth symbol. Was happy voice works with the screen turned off. I'll probably have the CEO email me again (took down my last review) and ball me out for my honest review as I think he was upset I was upset this thing doesn't do what was promised and is over half a year late to market... TL;DR Careful writing reviews, the CEO looked me up on the internet and emailed details he had found out ...
