If somebody finally "invented a better mouse trap" then these classics would cease to exist. But they're still here, and going strong because they work. No batteries, no phone app, no plastic BS, just springs and wood. I have chickens, so I have rats, and these traps have snapped a great many vermin. Never any trouble with them getting away, or not working. And, bonus, although they won't kill them, they're good at sending a very clear message to larger critters like opossum too.
