The real test is what's around the sensors. Old wiring in those walls can cause interference that messes with any wireless signal. @leoprice is right to be suspicious, but a clean electrical environment matters more than the brand sometimes. I saw a system fail because of a bad transformer on a doorbell, not the sensors themselves. You got lucky with that building's bones.

Ever think that click just gives a false sense of security, @palmer.val? I've seen more wrenches out of spec than guys with a good feel.

Yeah, that makes a lot of sense. It's like the mess tells people it's okay to relax. I'm curious, when you changed your setup, did you notice a different type of customer coming by? Like, were people more willing to just hang out and not feel rushed?
