Repel Intruders with an App-Controlled Lock That’s 10x Stronger Than a Deadbolt: $297

We have an interesting device for our deal of the day: the HAVEN Connect Lock. This app-controlled lock was designed by U.S. Special Ops veterans and mounts at the base of your door. According to the company, it reinforces your door with a flexible locking wedge that pushes back and uses an attacker’s energy against them. You can operate it with your foot or the companion app. This device is $349 through our deal, but coupon code MERRY15 at checkout takes 15% off, to bring it down to $296.65.
