Awesome router. This model has 4 functioning USB ports, so you can tether 4 cellular devices at once. This device replaced my Cradlepoint MBR 1000. It was so much easier to set-up and has some very useful functions that weren't available on the Cradlepoint.
I have 2 Hotspot devices directly tethered to my Pepwave. The Pepwave has a functionality that allows you to run off of both devices simultaneously or you can designate one to run at time. I have it set up so that once my monthly allowance is reached on one, it automatically switches to the other. This is so useful for me as I have incured some serious overage charges in the past.
The guys at 5Gstore were great in helping me choose the right setup for my situation.
