ZumSpot 3.5 awesome little HotSpot!
The ZumSpot does not have an integrated battery unlike the OpenSpot but this is not a consideration for myself as the primary use case is at home. If I want to operate mobile I can bring a USB battery with me to power the ZumSpot.
The ZumSpot 3.5 has a small LCD display showing which reflector you are linked to, including the frequency the ZumSpot is running on.
I am very impressed with how well the hot spot is working and how easy it was to setup.
The manual can be found here for those that are interested in reading more.
Overall big thumbs up!
