I got these wonderful personal alarms for my daughters since they are out late at school, work, and sports events. They work great. Super loud alarm sound and includes a bonus flashlight on it so they can find the door key hole easier. Arrived quickly. Tested loud alarm, easy to trigger And easy to replace pin to silence. Bright led flashlight with easy to use button. Everything tests out as promoted, just hope they don't need to use it for a real emergency. Peace of mind. This would be a perfect gift for a student going away to college or just for a person that lives alone and travels out late at night. Now a days you cant be to careful. You never know when your going to need to deter someone from doing harm to you or a loved one. I would definetly recommend. I am going to purchase one for myself since I really don't believe in carry a hand gun.
