This is an Amazing System

Great siren I've installed four of them and they have all worked great. The users have loved having them out of sight and just using the remote. With new LED lights and their low power draw controlling the lights with the remote has been even better than before.

Great siren for the money and love the wireless aspect of it. Super easy to hook up, very loud and good tones!

Great wireless siren

I thoroughly read the instructions and installed exactly as specified, including charging the remotes for 12 hours before use. The unit has power, but will not connect to the remotes, so it is useless. I am returning and I have ordered another, because no one else has given this product a bad review, so I will give it another shot. I will update when the new one arrives. ***UPDATE*** I ordered another unit and returned the first- it now is working as advertised.

Perfect! PA system works great and the dual remote controls works great

Wow-- it worked as advertised-- I can turn on all functions of my Police Unit up to 100 feet away -- great unit--

Have had this in two vehicles and works great, the remote works anywhere near or in the vehicle .
