I've got to say, the Zigstar UZG is amazing. It completely fixed my issues with Zigbee devices dropping off the network. Since I started using the Zigstar UZG as my network coordinator, everything has been running smoothly. What impresses me the most is the stability it provides. I no longer have to worry about my devices disconnecting. The user interface is super easy to use, which makes managing the network a breeze. Thinking of buy another to try as a router :) Overall, the Zigstar UZG has been a game-changer for me.
