Very pleased with these INSANELY loud alarms!

Michelle S. – Sept 3, 2023

I purchased these because my mom is always walking early in the morning and also for myself because I am often in a train station parking garage at 2am alone. My mom said she felt a lot safer while carrying this with her pepper spray and I think that’s great.
Yes, I recommend this product.
