I had a few AC Pros in a 110+ year old house where other AP’s had issues with all the plaster & lathe walls. They worked great. I also have a couple of them installed at a non-profit org I volunteer with and everybody is very happy with how they work there as well.

After moving from that first house to a new one with a bigger footprint I upgraded to a pair of their U6 mesh AP’s, one at each end of the house. Never had any issues with them.

So how would you use it to solve this problem? There still needs to be some sort of foolproof way of saying “person X is only 14 years old”.
