SHvivik Emergency Whistle, 2PCS Premium Safety Survival Whistles with Lanyard Keychain, High Pitch Double Tubes for Outdoor Hiking Camping Hunting Fishing Boating

I was initially very impressed with the appearance and design of the whistle, as the product photos gave a strong impression of quality; however, the actual performance has proven to be very poor. The sound produced is extremely low and ineffective, making it unsuitable for use in sports playgrounds, construction sites, or any environment where a loud and clear signal is required. We tested it in Flagma control operations, but the whistle failed to deliver the necessary volume to attract attention or ensure proper control, which defeats its intended purpose. Considering these shortcomings, I strongly recommend that the technical team thoroughly review the design and functionality of the product and implement serious rectifications to improve sound output and overall effectiveness at the earliest opportunity.

Great value, very loud and solid quality

Very compact and loud whistle I use it on my keychain for my Sea-Doo

Great alarm whistle. Works well and is a very ear piercing sound in case of attack. I gave them to my daughter and all of her friends for safety when they are out at night. Better safe than sorry.

This has a nice shrill sound. Got this because I had a scary incident in Chicago area grocery store parking lot. Another safety device I carry
