I used to travel alone a lot and I have pepper spray but I never thought about one of these alarms until I saw these. I'm keeping one for those times I'm out and about on my own and giving the others to my nieces and daughters-in-law.When I tested one, I couldn't believe how loud and piercing the sound was. It's perfect for someone needing assistance. They might even scare someone away.

So impressed with this product! It’s an amazing value for the price. The alarms are small and light enough to go everywhere with me. Plus I was able to give one to both my sisters. They come in a variety of bright colors and hook on a keychain easily. The flashlight feature is super helpful but the real benefit is when you pull the alarm. SO loud. Just as loud as the motion sensors we had on our sliding glass doors growing up. There’s no way this alarm would be missed if you had to use it in an emergency. Totally recommend.

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!
