I have spent hours on the phone with Luma support (very nice people) and was never able to get it to work. Luma Support sent me new ones and the same result. I spent hours of time doing all kinds of different things but with the same result. In fact, at the end, we decided to start over. The app would not let me create an account (hahaha). They just don't work.
Bottom Line: No, I would not recommend this to a friend
This is because of the traditional mindset to configure a router. Just step back and think like a non-techy person. It's a breeze.
