When it was introduced in 2016, the Luma was a bit overpriced. Two years later, a pair can be had for $30-$40 a piece. I bought two pairs in August 2018 for $130 total, and they work great, connecting over 4000 square feet, including a basement and garage, over three levels. Setup took less than 30 minutes, including downloading the app. Consistently get at least 50-80M throughput.
Are they the best? No, but they are very good, high quality, and you cannot do better at their current price point.
Bottom Line: Yes, I would recommend this to a friend
