Luma is a significant improvement in coverage and throughput. I went through may routers and extenders, ending up pretty good coverage around the house, but there were dead areas, and one had to continually switch access points with different SSIDs. With Luma, there is complete coverage, significantly faster throughput, and just one SSID, so no switching! The system also seems pretty good at allocating bandwidth among devices and managing conflicts. I'm glad I got it.
Bottom Line: Yes, I would recommend this to a friend
