GREAT UNIT SO FAR
*update after 2yrs usage* everything I stated below still holds true. Buttons haven’t worn at all* Only had it for about a week so eventually I’ll update. For now I’ll do a pros vs cons Pros: *PA is very clear *well built *Lightweight *Buttons are not super firm, they’re balanced well *Sirens sound very professional *Comes with STL LED flashlight *Install was VERY easy. “RED positive, BLACK negative, & both BROWN wires go to the speaker.” Cons: * wires could be longer and that’s my only con at the moment but it’s no big deal buying speaker wires in my opinion lol. Summary: it’s a great unit for the money and could go well for volunteer firefighters or personal police/security vehicles. I’m using this unit with the 100W Yhaavale flat speaker and it’s VERY loud. I’ll probably use the STL version in the future. I’ll leave a video below on the sounds. I hope that this helps anyone interested in the unit. Thank you STL!

Good unit
Very nicely built unit. Small enough to fit almost anywhere. I like that the buttons are backlit makes it easy to see at night. Good value for the money.

Sounds good but the video has inaccurate sound
Great quality and sounds good but the wail sounds nothing like the video shows
T**.
better than expected.
just to clear up, you get the box with the dual horn. the lower pictures had me wondering. siren projects well with a lamphus 100w speaker, not sure if different speakers will do better or worse. box is small enough to make for several mounting options, but not so small that you fumble trying to control it. buttons have a tactile press, as does the horn rocker. pa is loud and clear, excellent build quality, would definitely recommend.

Great product
Works perfectly and as described. Only reason I gave it a 4 star was because would like the blue lights on buttons to be brighter

This is a great sounding siren, and comparable to a Wh*len. True 100 watt siren.
The mechanical siren sounds more like a dying wild animal, but the rest of the tones sound like the American competition. Really a good sounding siren that clears traffic. Used with a Feniex 100 watt speaker. Fits inside the center console of a 2023 Honda Odyssey. The PA microphone looks cheesy though....
