Personal safety has become more and more at issue. Taking reasonable precautions where and whenever you can is a realistic thing we need to consider. These small alarms pack a BIG sound and can make a bad situation better. I bought a package of them to give to some of my close gal pals. Each lady was enthusiastic and appreciative. We briefly chatted about circumstances where problems might occur and how to use these little alarms if needed. Because of the size and shape of this Personal Alarm it can fit just about anywhere. Purse, pocket, backpack, in your vehicle, or even in your hand just names a few. I plan on getting more for other friends as well as for myself so they are always accessible to me in a variety of locations. I don’t want to become house bound because of fear so being prepared for circumstances that are beyond my control is a healthy action I choose to take while I’m out living life. I wish you all a safe and happy life.

My husband purchased this COSIN SOUND ALARM product in SEPTEMBER 2019 for our personal use since we both travel a lot, locally and internationally. In fact, I have almost forgotten about this gadget until it worked its function today, this early morning of JULY 25, 2020, Saturday. You would think that it is just a tiny thing, but boy it was so loud and very powerful! It gave us the security we badly needed at the time we needed it most!BACKGROUND INFO:1. We were at home sleeping soundly when suddenly our motion sensor at our fire escape went on. The music alarm was loud it woke us up. So, we got out of bed. Checked our security camera from our iPads.2. Yes, there was an intruder downstairs. There was a car that pulled into our alley!3. At 2 AM, the heart San Francisco where we live was still very much asleep and quiet.4. In our security camera, it showed that a white car stopped right in front of our fire escape that leads to our veranda which leads inside our domicile.5. FYI, the fire escape ladder is fixed on the floor level. Very inviting to the bad elements. This is why it was imperative that we had the security system installed.6. The car was there, canvasing our place. Across us is an office building and the other buildings within the alley is residential. With all buildings’ security lights being on didn’t scare off this white car/intruder/s.7. As the time moved on, my husband and I were in tandem. We did our protocol.8. I grabbed my KOSIN Safe Sound Personal Alarm and pulled out the lock and bingo! The loud sound went off!9. I ran fast to the veranda and placed the KOSIN Safe Sound Personal Alarm out there. Then, watched the car downstairs…what would the intruder/s do?10. Suddenly, I saw the white car backing off as fast as the driver could! The KOSIN Safe Sound Personal Alarm sound was way so loud that they/he/she heard it quite well, despite of the fact that the car was closed and the windows as well. So this shows and proves on how powerful and loud this KOSIN Safe Sound Personal Alarm is!11. That did the trick!EPILOGUE:Who would think that such a tiny object could work its wonder?Honestly, I never thought that a day would come when this gadget would be so handy and useful to me and my husband. And that has proven me right today! I hope that I would have no use for it in the future. But one never knows so I’d keep it close by and handy!LASTLY:I highly recommend KOSIN Safe Sound Personal Alarm for its powerful make up, and it serves its purpose which is to scare away the bad people!!!!I want to thank the manufacturer of this gadget. It is superb, great quality and very functional!

Definitely loud so if I need it I know they’ll do the job. Just a little big on my keychain so I carry it separately.

I bought these as gifts for my entire family. Love the siren on them and they can be carried on your purse or keychain. Great buy.

These are the loudest I have found, including name brand attempts.I love the multi-pack. I hike a lot and have multiple backpacks, so this allows me to put one in each pack ensuring I don’t forget it.I love that it has a flashlight, worst case scenario back up for my headlamp.Tips:* Attach the gray strap to the keychain, like shown in my picture. This way if you accidentally pull the pin, you can easily find and reattach it without too much embarrassment (ask me how I know 😆).* Always test first, and store it somewhere the flashlight button can’t be pressed easily. The battery can run out if you accidentally push the flashlight button too often, or have it held down (like pressed against something in your purse).The 2 negatives:I would prefer these to take a single AAA battery which was easier to change.It would be nice if the flashlight button was recessed, or otherwise prevent accidental activation.

Great safety gifts for anyone. It works, attracts attention and super loud it even scares me.

It is loud which is good but the picture shows a button which I wanted – it’s not real you do have to pull the side thing and putting it back in to stop it takes practice.

My daughter and I tested one out. We pulled the plug and let it rip. I was very loud and the plug went back in and it was quiet again. I gave one to my five closest friends. And told them I hope they never have to use them would be great for stocking stuffers for the older crowd or even the younger crowd I see the girls or boys could wear them on their backpacks or anything like that the possibilities are endless. And it has a little flashlight on it it would be great on your keychain because if it was dark and you had to use a key entry I love them !!!

I bought these on a whim for both of my parents to attach to their walkers as a temporary means of alarm until we can get a more permanent medical alert system in place. Quite loud which is what we were looking for in case one or the other were to need help.
