I recently installed the Feniex Typhoon Handheld Siren & Controller in my vehicle, and it's been an outstanding addition to my emergency response setup. Right out of the box, the unit feels well-built and purpose-designed for real-world use — compact enough to fit in tight spaces, yet rugged and ready for frequent operation. One of the things I love most about this system is how intuitive the handheld controller is. The programmable backlit buttons make it easy to activate tones and auxiliary functions even in low light, and the integrated PA microphone adds real flexibility without needing extra accessories.
Excellent service, I ordered my items online, and received great progress reports and shipping reports. Was advised of when items were going to ship and they arrived as ordered shortly later. Thanks to everyone involved.
These lights FAR surpassed our expectations for brightness, and installation was a breeze. We are very impressed! Chief Roberts Utica Vol Fire Dept
