  • Olivia, Glasgow 21 August 2025
    Simple, powerful, and reliable
    I tested it as soon as it arrived — wow, it’s loud! It’s comforting to know that if anything happens, I can alert people instantly. The battery lasts ages too.
  • Emma, Manchester 24 August 2024
    Such a smart and discreet safety companion
    Compact, stylish, and powerful — I clip it to my keys, and it doesn’t draw attention, but when needed it works flawlessly. The Bluetooth SOS feature really saved me during a nerve-wracking moment. I’m so glad I found it.
  • Claire, London 28 August 2024
    I finally feel comfortable walking home at night
    I bought Sirenly after seeing it in a group chat. The siren is incredibly loud, and knowing my closest contacts will receive my location gives me real peace of mind. I wear it on my bag every day now.
  • Sarah, Liverpool 7 September 2025
    Perfect gift for my daughter
    I bought Sirenly for my teenage daughter when she started college. She loves how it looks, and I feel more at ease knowing she has this extra layer of protection.
  • Lucy, Bristol 12 September 2025
    A must-have for every woman
    I wish I had discovered Sirenly sooner. I used to feel nervous walking home after my evening shifts, but now I feel protected. The alarm is super loud, and I love the peace of mind it gives me.
  • Zara, Birmingham 13 September 2024
    Amazing product & fast support
    I contacted support when my device didn’t connect immediately. They responded within hours and solved it. After that, I tested it in a quiet area and the 130dB siren is just shocking — in a good way. Feel safer every day.
  • Megan, Nottingham 28 September 2025
    Brilliant for runners
    I take it with me on my morning runs, and it’s so lightweight I barely notice it. But it gives me so much reassurance, especially in quieter areas.
  • Jessica, Cardiff 2 October 2025
    Great design and easy to use
    It looks sleek and modern, and attaching it to my handbag was super easy. Setting it up took just a minute, and I feel a lot safer walking home now.
  • Hannah, Leeds 3 October 2025
    Gives me peace of mind every day
    As a university student, I often walk alone late at night. Having Sirenly clipped to my bag makes me feel much safer. It’s small, discreet, and so easy to use.
  • Emily, London 9 October 2025
    Highly recommend to all my friends
    I’ve told all my friends about Sirenly. We all carry one now. It’s affordable, reliable, and gives us the confidence to go out without fear.
