JOHO Stainless Steel Door Stop Alarm: 125dB anti-theft sensor
Available Options
Imagine a security gadget that doesn't need Wi-Fi, batteries, or an app to scare off intruders. The Stainless Steel Door Stop Alarm is exactly that—a no-nonsense, mechanical sentinel for your door. When triggered by an opening door, it unleashes a 125dB shriek (louder than a chainsaw) that's guaranteed to startle would-be trespassers and alert everyone within earshot.
Built like a tank with stainless steel, this little wedge laughs off tampering and brute force. It's the ideal travel companion for the security-conscious, slipping easily into a suitcase for use in sketchy hotel rooms, Airbnb rentals, or college dorms. No tools, no installation—just wedge it under any door and sleep soundly. For those who prefer their security simple, loud, and utterly reliable, this is the gadget that delivers.
