MegatronixPZ9 12Volt 110db One Tone Electronic Piezo Car Alarm Security Siren

Extremely easy to install , the size is perfect , the housing feel solid and durable . I would have preferred a cable instead of 2 wires (red/blk ) but I wrapped it in heat shrink ....I installed this under my motorcycle seat and tied it into the factory alarm on my Harley Vrod . The sound is very very loud and ear piercing ( the cat jumped up 5 feet in the air and looked for cover ).It’s not a horn siren like a car horn , but intsead a high pitch ear piercing sound .It’s not at all annoying when I arm ( 2 tiny chirps, that’s a function of my Alarm ) it’s discrète and confirms it’s set .I am confortable knowing that if someone was to roll and try vanning the bike , it would attract attention and deter the thieves .I would highly recommend this little noise maker .

works as advertised, good product

I installed it on my 2019 Harley-Davidson Street Glide Special. It was very easy to install. It is very loud and functions awesome. Very well pleased. I placed a video on Facebook and what a response. I probably sold several for your company.

Not the sound I'm use too for an alarm.

A little low and small but doea the job.I use it to test continuity in circuits in my job and it works .just need to make a case for it so i have a place to fit 9volt battery.But overall this works as discribed , arrived quicklyThanks

Works great, fast shipping and can't beat the price. I wish it was a bit louder but what did I expect from a tiny siren. Installed on my 2010 Harley Davidson Street Glide

Works exactly as described, and for the purpose of placing an alarm on my Harley in combination with the security system....works great.

Great little speaker. Addis it to my Harley’s alarm system. Works perfectly!
