We have had one for two years. It’s cell reception really isn’t much better than your cell phone and you have to be very careful that the limited LTE bands it receives are going to achieve the connectivity you want with your provider. We use a google fi data only SIM card which really is T mobile and it does work, just not all T mobile bands are supported, which is a problem when your on fringe areas - just where the glomex should shine, but instead it falls flat and reverts to 3g. The auto switch, from LTE to dockside wifi sounds great but we have problems with the router dropping its wifi signal constantly when it is in this mode. Product support is zilch to none so you pretty much have to figure any problems out on your own.
