These work well to get a shed over 200m away from the house connected to the NBN. The speed is 6x faster than my 50Mbps plan, so plenty of spare. They claim to work up to 29km, but I cannot test that.
I do wonder about the robustness of the materials. They feel more like indoor consumer products than outdoor devices. I also have doubts about their ability to withstand the hot Aussie sun. We will see.
Mine still work after 1 week. I will update if/when they fail.
