And practice regularly. It's loud enough to attract attention of other people nearby, but it's hard to imagine it "scaring off" and attacker by itself. Usually these guys are pumped up on adrenaline at that point, and this may give you one moment to change the dynamic with a brief surprise at best.

I like the design of this one and the strobe light feature, but the volume was not nearly as loud as another, smaller product I bought, so I returned this one.

This is like auto and home insurance. Need to have it but hope I never have to use it.Easy to hook on purse.

This device caught my attention and so decided to buy one for my wife and granddaughter. The look isn’t obvious as to what it is, but it’s loud enough to get someone’s attention and run a bad person off.

Lightweight and easy to use and carry! I thought it would have been louder!

I’m not impressed with the sound emitted from this device. If I were on the sidewalk and residents were in there homes with windows closed they are not likely to hear this.

Purchased for myself and granddaughters. Alarm is very light weight and fits in palm of hand. Tried alarm and WOW I jumped it was so loud. The pin portion snuggly fits into base so it won’t accidentally fall out; however easy to remove should alarm be needed. Comes with a clip to attach to purse, wristband or I bought lanyard to use when walking. Just adds a little peace of mind ~ I pray they are never needed.

Great product I just wish they were a bit louder!
