Review on Upgraded Traveling Security Stopper Doorstop by Mike Modesto

Super price for 3! They're certainly loud enough to wake a person up, maybe stop a predator and prevent a crime! I like that they can't be hacked either. All too often, Wi-Fi and all of our "trusted devices” on the internet are compromised, hacked, monitored, bugged, tracked, monitored and used by technology – all too often they are targeted and potentially at real risk. A false sense of security is very dangerous. They provide a simple signal, a warning that cannot be hacked/silenced by others! Good product, great price - security is priceless.
