Review on 🏃 Atlecko High-Visibility Personal Safety Alarm 140DB for Runners, Men, Women, Kids, Elderly - Loud Siren Sound +300M Emergency, Self-Defence, Security, Panic, Rape Attack for Running, Walking, Cycling by Stephen Cooper

The security alarm is great for my wife who runs in the morning but when I received the item the alarm didn't work (I removed the paper tab). After unscrewing the back and checking the batteries, I found that they were already leaking a bit, which may have caused the problem. So I took them off and cleaned them as best I could. Once assembled it worked fine but I fear durability due to corrosion. Otherwise a very good product and fast delivery.
