Yes it was, I very much loved it and was disappointed when we had to let it go.
Thank you 
Seems like you were pretty comfortable with Asus and TP-Link.
What factor(s) flipped your decision to Ubiquity?
I missed this thread, but let me add to the chorus of people who REALLY LOVED IPNetRouter. Not only did it work well, but I learned a lot about network management and firewalls, etc, by configuring and monitoring it.
If Apple were to bring back its networking hardware (which they should, given Cook’s policy of ‘control the major parts of the stack’,) they should install IPNetRouter-like functionality into a new-and-improved AirPort.
I had to upgrade my mesh from what my isp provider gave me as I wasn’t getting the coverage I needed. I tried T-P Link and it was awful. I then went with EERO 7 and it’s fantastic, but expensive.
