Bests & Worsts Reviews from Amazon

I have three personal alarms including another one made by this company. While the other two are "okay", this one definitely is better. It's not as loud as an ambulance or jackhammer. That's not true. But it is definitely sufficiently loud. It is enough that a criminal is not going to stand there and put up with that sound. In a crowd, someone will notice. I set mine off in the house and my unshakeable dog looked at me like "What heck just happened?" And he is not usually sensitive to flash lights, I pointed it at him, as it is not a laser, in full day light and he squinted because it was so bright. I put it through it's own loop on my purse strap. So it's right out there and obvious. I like the grenade pin activation and I especially like that it takes AAA batteries unlike all the others that take weirdo button batteries. So jackhammer or ambulance loud, no. Obnoxious and annoying enough to scare someone off, DEFINITELY. I am thinking of buying another for my sister who is handicapped and can't really fight anyone off because no attacker wants to be seen or heard and you would definitely been seen and heard as much as you possibly could off of AAA. I mean it's really really obnoxious to the point that it would draw a crowd. I really think these would be good for someone who wants something to protect a teenager or handicapped person that couldn't be used against them in anyway such as pepper spray or a stun gun. And I do martial arts and you could always clasp this thing in your fist and beat someone with it if push came to shove, it's big enough and harder than your hand.
