This is a little holder for a Karma Go hotspot (full disclosure: that's an affiliate link that gives you and me a $10 discount). The device slots in and fits snugly. The status lights are visible on top, and the charging port and power button are accessible on the side. The back of the holder is flat, so it's easily mountable with double-sided tape.
I use this in our family van, so the kids can watch Netflix during road trips, and the hotspot doesn't take up any precious space in the tiny dashboard compartment, yet can remain plugged into the charger. I'd previously tried just using velcro, but the constant vibration meant the device would randomly detach itself and roll across the floor. Kind of scary when it rolls under the brake pedal. This holder should keep it secure while still making it possible to easily remove the device when actually desired.
This holder may also work with the FreedomPop Freedom Spot Photon and Clear Spot Voyager, as they seem to have the same form-factor, but I have not tested either of them with this holder — I've never even seen them in person.
