Review on KOSIN Safe Sound Personal Alarm - 8 Pack 140DB - Powerful Security Keychain Alarm with LED Lights - Emergency Safety Alarm for Women, Men, Children, Elderly by Matthew Ciula

We live by the sea. I dare not check these things in the neighborhood. We'll have to wait for a day without rain and go down to the beach to test them. Don't worry - I will wear hearing protection. Lets you know how loud they really are in the revised rating. In an amended review. Today I was on the beach road. Too many people on the beach to check those alarms. Since it was Sunday, I went to the nearest light industrial park. I parked my SUV in the driveway to the closed office. He opened the back door and put on industrial-grade hearing protection. Turned off the first alarm and pulled the plug. Not very loud. Safety plug plugged in and pulled out another. The same - not very noisy. I had a DUUUUH moment. I had industrial grade hearing protection. While the little alarm clock buzzed, I took off my headphones. HOLY COW, BATMAN! These little kids are LOUD and very annoying as some of the sound patterns are modulated to sound like an ambulance. By the way, I took a few small things with me in my SUV in case I need something to insert my safety pin. I also took a hammer in case I couldn't get the pin back in. When that happened, I had to destroy the alarm that wouldn't allow his needle to be reinserted. 30 minutes. Luckily all worked fine and all accepted the safety pin which they tucked back in. After my test of all 8 I am very satisfied. away, it's a safe bet the villain will kill himself trying to climb out the window to escape. In fact, unless it is a life or death emergency, you should NEVER operate any of these devices indoors. Once you turn it off, you and your family may see an ENT doctor for a hearing test. you are so loud May damage unprotected hearing within structure. I was also outdoors in an industrial area during my test. However, they were so loud - at arm's length - without industrial-grade hearing protection that I felt a certain discomfort in my ears. I will buy another box or two for my family members.
