TECKNET BASICS إنذار سلامة شخصي، 130dB سلسلة مفاتيح دفاع عن النفس مع ضوء SOS وامض، إشعار انخفاض البطارية، صفارة عالية للنساء والأطفال وكبار السن، أزرق

Bought this for my daughter's walk home from campus and the strobe light is what sold me, it's blindingly bright even in daylight. The low battery notice is a nice touch too, no surprises when you actually need it.

The 130dB siren is genuinely ear-piercing — I tested it once in my car and my ears rang for a minute. The strobe is bright enough to be disorienting even in daylight, which sold me on keeping it on my keys.

Clipped this to my daughter's backpack for her walk to campus, and the 130dB siren is genuinely deafening when I pulled the pin to check it. The little strobe light is bright enough to be seen from across a parking lot too.
