Review: Much greater range and speed - I had to add a desktop machine in the far reaches of my shop, where there is presently no Ethernet access. A USB3 mount was 3D printed to run a cable outlet to the top of the monitor, but even with that, the spare EDUP 600Mbps could not connect on the 5ghz band, only 2.4. That limited download speed to 20-25Mbps and uploads to less than 10. There is a lot of metal and other structure between this PC and my beastly ASUS ROG router. Downloaded and installed the TP-Link driver, and plugged it in. Voila, hits 5ghz with full bars and downloads are 10X speed at this distance. Uploads are nearly 20x. Quite happy with the performance. Beamforming is a thing. Only disappointment is that the photo shows the folded up antenna as silver, which matches the body. The folded up belly of the flip up antenna is stark white, so aesthetically it's not attractive. But that's a minor price to pay for the connectivity performance boost.
