I love this keychain. It's a little bulky, but not heavy so it doesn't add a lot to your keys. After taking the tab out, I tested the alarm and it is quite loud (as promised). The pitch will change if you change the direction of the sound opening. I hope I never need this--but as I work the evening shift at a hospital, this will be great to have in hand on the way to my car.

As soon as I received the alarm I tested it. It sounded almost as loud as our car alarm. The noise should fend off an attacker or at a minimum alert others about the danger. It's lightweight and easy to use. The black button on the front activates the alarm and a similar one on the back deactivates the alarm. I clipped it to my everyday purse and will definitely take it with me on my travels.

Bought one each for my daughters and myself and so far we are pleased. I like that it has the whistle as an option. And the alarm is a little different from most car alarms, that most of us ignore, so others more likely to take notice. Only criticism is that it’s a bit larger than I’d like.

I bought this for my daughter who was going to start riding the bus at night in the Twin Citites. Thankfully she hasn't had to use it yet but it is definitely loud enough to get everyone's attention! The dog disappeared when we tested it...lol I also really like that the back up manual whistle is very loud. Now I don't have to worry about the battery dying.

I just got this, it was so easy to pull the plastic out of the battery area and it is so loud. It was easy to hook onto my jacket's zipper tab, very light weight, whistle easy to use. Have to update on the longevity of it.

works well, I use it to get my kids up in the morning....just kidding, sound is loud, price was right it's a good deal!

Just having this on me I feel safer while out walking with my dog. The only thing is one day I leaned against the counter and since I wear it on my waste, I set the alarm off. That racket would certainly draw attention. and it turns off real easy, once you rememberf where it is. A Great product

This one does require yu push a button for the alarm, but I would rather have that, than have one that will go off if someone or thing yanks on it. Accidentally. I'm not willing to risk that.

Very LOUD and easy to use! A bit too easy actually as have activated it accidentally just by looking for something in my purse and touching it! Certainly gets people’s attention which is what I want since I walk my dogs at all hours of the day and night.

boy, this is LOUD! Just like your house fire alarm would sound! Hope I never have to use it though. =) FYI, the big red button is just the plastic casing--in the picture, it looks like you would push the "red button" to activate it, but you don't. It's the little black button (slightly recessed) that activates the siren. On the backside is the deactivation button. I have a HUGE purse and a HUGE keychain, and throw my keys around a lot, but it NEVER accidentally activates. Great product!
