I was a long-time Airave user. I always had problems with the device not getting a GPS lock and thus refusing to work. When I got a Galaxy S5 with WiFi calling I stopped relying on the Airave. I've since moved to Project Fi and haven't looked back. This new device looks like it receives service from a nearby Sprint tower and uses it to serve your home/office. That wouldn't have worked at my home where it was nigh impossible to get Sprint service even when outdoors.
