Swapped to screw terminals from wire nuts for panel connections - never going back

Used wire nuts for years on every alarm panel install until a service call in Phoenix last July where heat had loosened one and caused a false alarm. Swapped to screw terminals on that same panel and haven't had a single callback since. Anyone else made the switch or still sticking with wire nuts?

What's driven me nuts about wire nuts in panels is how they can work loose over time, especially in any kind of temperature swings? I made the exact same switch after a similar heat-related issue and it's been rock solid ever since.

Respectfully, nuts don't work loose if you torque them right.
