I used Calyx hotspots for 2 years. The hardware they offer is garbage and Sprint coverage is spotty.
The Franklin R850 is outdated and unreliable. I had one and hated it. The ZTE hotspot they had after that wasn't terrible but the charge controller was bad and would overcharge the batteries. Now they're back to the terrible R850 since ZTE is banned. I can't speak to the R910 but after my experience with the R850 I never want to own another Franklin product.
I may get another unlimited Sprint or T-Mobile hotspot since they're good for high bandwidth activities (eg streaming video) when the signal works.
