Neat portable personal alarm
Nice neat portable alarm, I tested the noise it emits, very good. I have it attached to my bag, it's nice neat size, very lightweight . Only small downside is it's not rechargeable, need to replace battery. I knew that when I purchased it. Am hoping I will not have to use it. Quick and efficient delivery.

Good but no that loud

Loud but too easy to activate
Looks very nice. Works well. Would definitely scare off any potential attacker. Only problem is it is far too easy to set it off so I don't take it with me. You only have to touch the top bit that you pull out in the wrong way and it goes off.

WHEN CHANGING THE BATTERIES THE ACCESS SCREWS ARE SO SMALL IT IS ALMOST IMPOSSIBLE TO REPLACE THEM.
USED AS A PERSONAL ALARM. bUT FOUND IT IMPOSSIBLE tO REPLACE THE BATTERIES AS ACCESS SCREWS TOO SMALL TO REPLACE. ALARM WAS SCRAPPED AND REPLACED WITH A RECHARGEABLE ONE.

Super loud shrieking sirent, bright light and lasts for hours
At 2am, a friend and I were doing an 18 mile high alpine hike in the spring mountains, NV. we were hiking towards Mount Charleston Peak when we noticed two big yellow-orange round eyes about 150 feet away behind a log. The eyes were about 2 feet off the ground, and then the eyes went lower to about a foot off the ground—It crouched down! Although I could not see the entire body, the part of it we could see was big and long like a deer but his face was round, and he was very low to the ground and then went even lower. I handed my friend the can of bear spray which she pointed in his direction. There was zero wind at this point on the trail so I told her to deploy the bear spray if he comes toward us. I then took out my 45 Ruger handgun from my backpack waist strap pocket and changed it from “safe” to “fire” mode. This is the first time I’ve ever removed my gun from my waist strap pocket during a hike. I told Jenn I would fire a warning shot to the ground near him if he got closer. As I was getting the gun out and removing the safety, he crossed the trail about 100 feet in front of us and was now positioned to the left front of us, closer than he was before. He was about 80 feet away from us behind another log crouched down looking directly at us. At this point I was VERY concerned because he moved closer to us, he crouched down, was staring at us and he wasn’t leaving. We started quickly discussing options. Should we back up, should I fire a warning shot? Yes yes yes we agreed. We agreed to slowly back up which we did and I decided to deploy my siren/strobe light before shooting a warning shot. when I pulled down on my personal alarm/strobe light that is attached to the left side of my backpack strap, it immediately lit up, flashed bright flickering lights and started shrieking a 135db high pitched alarm. The moment I pulled it, he ran off.For the next hour and a half we cautiously proceeded on route and kept the alarm blaring for over an hour and a half until we were on the ridge and no longer in an area that had trees.This device scared off the mountain lion that had approached us and wasn’t leaving. He only left after I deployed this device. I’m so thankful I had this device in this hike.

Good device...but I think a small change would make it better!
After receiving the personal alarm I have one observation. I bought this for my 18 year old daughter and my wife as part of some deterrence. I looked at this device from an Engineer point of view. My 2 cents is that the part that should have the clip attached is the body of the alarm and not the pin. If the body of the alarm is clipped to your person, then you just need to pull the pin and the alarm stays with you. With the current design, the pin is clipped to your person and the alarm is pulled away. That means it could more easily be taken away and stomped on or thrown away. I wish it was just a little bit louder but it should bring attention.

Awesome alarm
This little alarm is great! I love that it comes in a variety of fun colors. It was for my mother’s birthday and it came in her favorite color. It is light weight and very easy to use. It is very well made and will last her many years. The alarm works the second the pin is pulled and is very loud, it would definitely scare someone trying to harm her. It also takes a little bit of precision to get the pin back in, I do not think a nervous car jacket or someone would be calm enough to mess around with it to get it back in to place. It is a very small hole and it has to be lined up exactly right to click back into place. If you expect the sound it’s easy to do, by in a high stress situation with shaky hands it’ll take a bit of time! My mother likes to walk in the woods but has become very nervous about it and has been feeling uneasy. Since getting this alarm she’s back in nature and feels very safe to be there. She said it is one of her most favorite gifts she ever received. I will definitely be buying many more of these. Going to use them as stocking stuffers for my older children and will be getting them for many friends and family members as well. I’m extremely happy with this purchase!
