Loud. Bright. Just Right.
Very loud and very bright. My wife has to travel sometimes and when she's alone I'm thankful for anything that might help to keep her safe.

Easy to use
Very loud and attracts attention, which is what it is designed to do. Pretty, easy to clip on to keys, purse, etc. and gives a sense of security in a potentally dangerous situation

EDIT-cannot replace battery🥹
I loved the concept of this little alarm and strobe light. I purchased three for my daughter and two for me. One on my keychain and One on my nightstand. Thank God, I never needed to use it, but I decided to check if it was still working properly. Unfortunately, the sound is very low and the strobe light is not bright anymore. Makes sense, Probably need to replace the battery right? Nope. I opened it up and to my surprise, I don’t see what I expected to be a little round flat battery. So now it’s garbage. Actually I don’t know at what point it stopped working loud, I tested it when I received it and loved it so I bought a total of five and spent $100. I just checked with my daughters, And she has thrown hers out a long time ago. I see that now they sell some that are rechargeable. That makes more sense. Regarding safety, I must know that whatever I have will work in the event I need it. So mine are going in the trash And will replace with the chargeable one. That is why I edited and Removed a star. When it comes to safety items, it should be clearly noted that one needs to test regularly to make sure the There are still enough power for the alarm and light. False sense of safety. Of course I know this is just for a moments distraction, so someone can get away, hopefully.

Easy to use
The ear splitting sound and the ease of use were amazing. Hang it in your phone because it’s in aesthetic colors too.

Yes, It's Really Loud!!!
Just received the Hootie Alarm a few days ago and tested it out! It does make a significantly loud sound that should deter someone from pestering you!!! I may give it to a relative this week and order another one for myself!

ALARM DIDNT WORK SELLER RECHARGED ME AND STILL HAS ALARM.
I ORDERED 1 PINK AND 2 BLACK ALARMS. ONE OR THE BLACK ONES DID NOT WORK AND I SENT THE ONE BACK THAT DID NOT WORK. THE SELLER IS SAYING IT IS NOT THE RIGHT ITEM THAT GOES WITH ORDER NUMBER. I DID NOT KNOW WHICH BLACK ALARM WENT WITH WHICH NUMBER SO I JUST PUT IT IN ONE BOX AND SENT IT BACK FOR A RETURN AND THE SELLER SAYS IT IS NOT RIGHT ITEM TO GO WITH ORDER NUMBER AND SHE IS RECHARGING ME FOR ITEM WHEN SHE HAS THE ALARM THAT DID NOT WORK. PLEASE GIVE ME MY MONEY BACK FOR ONE I RETURNED THAT DID NOT WORK.
