There are two others that I have been following, too. The Sonnet and the Gotoky. They are similar, but the Sonnet mentions the following:
In comparison to other off-grid communication brands, Sonnet has the following unparalleled advantages:
1. Sonnet is 40% cheaper than the second cheapest brand;
2. Internet-sharing: If one Sonnet within the network has Internet, it can share that with the entire network;
3. Sonnet powers all forms of data transmission: Not only text, but also voice, image, and ALL files;
4. Sonnet powers 16 mesh hops, far more than all the other brands;
5. Multiple devices can connect to each Sonnet;
6. Sonnet works with your computer and ALL Wi-Fi enabled device;
7. Sonnet can function as a stand-alone relay tower;
8. Sonnet is rated IP66, dust-tight and water-resistant;
9. Sonnet is extensible with the USB port. It supports many USB devices such as webcam, USB drive, GPS dongle, 3G/4G dongle, audio dongle, etc. ;
10. Sonnet has a SMA connector, so you can connect your own directional antenna to increase the point-to-point range even further.
We are proud to say Sonnet is the first to bring these amazing features to the world!
As a radio enthusiast, having an SMA connector is pretty sweet. I suppose it is simply too soon to predict which of these will actually make it to market. And, if any do make it to market, how well they will actually work.
There are some Beartooths in the wild now. A couple of reviews have been posted and they are not great.

At the risk of pointing out the obvious, they must be using an internal antenna on the Beartooth. It is no wonder they are getting poor range. I suspect the range is about what I get with my old Nextels on Direct Talk. Perhaps Beartooth should consider a better antenna. Even an external SMA antenna jack and a 900 MHz rubber duck antenna are bound to improve performance a bit with these. If nothing else, just a retractable antenna, like some of the Nextels used, might be an option. That way the end user could keep them collapsed, if they wanted, and extend them when desired.
