The wood and copper spring ones are total crap. The mice will steal food off them all day, I’m sure they’ve evolved to see them as traps by this point.

I’ve seen one of these things kill like 4 mice in a row. And it was all the same trap, on the same night!
Wood ones get picked clean consistently or set off with no kill. Victor ones require no skill. It’s like clockwork, set them and they’re dead immediately.
