This personal alarm stands out with its strong safety features and ease of use: With a sound level of 130 dB, it can emit a striking sound even from a distance, effectively attracting attention from bystanders and deterring attackers in dangerous situations. It helps you quickly get help when you encounter problems or need assistance. In addition, it functions as a mini-LED lamp: practical when walking the dog at night, unlocking the front door in the dark, or in other situations where a soft light source is needed, increasing your safety in dark conditions. 【Easy to use and keychain design】 The alarm is extremely easy to use: just pull out the contact pin to activate the alarm; after use, reinsert the pull ring into the opening to stop the alarm – no complex steps required, so anyone can quickly master it. It also has a compact keychain design, recognized by the police, with a stylish appearance that can serve as a decorative element – so small that it is almost imperceptible. You can easily attach it to your bag, backpack, belt loop, suitcase, or keys, ensuring it is always with you when you need it. The delivery list includes a personal alarm with a keychain, including 2 AAA batteries (ready to use immediately upon receipt). Regarding use and maintenance, please note the following: When the battery is low, both the alarm sound and the LED light will become weaker – remember to change batteries in time to ensure functionality. The product is lightweight and portable, meaning it is not an extra burden to carry.
