I needed a buzzer to activate with a DC electronic strike. The strike I had installed would click but was barely audible, and I needed it to buzz. Short of replacing the Strike with an AC strike that would buzz, I decided to look for a buzzer to add to the existing strike so I would not have to replace multiple expensive parts.This buzzer worked perfectly. it makes a decent buzz sound, not too loud, but not too soft. This is bigger than I had expected, but it fit where I needed it without issue. simple install just wired in line with the strike and when it is released this buzzes.This reminds me of the old car buzzers when you used to turn the key on prior to starting the car or if you left the headlights on.It worked perfectly for what I needed it for, and makes the sound I needed it to make.

Great application for a warning sound. My application is a lights-on reminder for a classic car.Sound: great buzzer sound - not the high pitch piezo sound you will get from the cheaper options aroundVolume: very subjective. I think the volume is loud if placed uncovered inside a car. Good volume for an under dash application.Comments: I read some reviews were the purchasers were not happy in a boat application. I can see that being an issue since this is a buzzer that works at a lower frequency but inside a car it works great.

I had planned to use this as a door buzzer for an old car, but ended up going a different direction. Regardless, this would have worked fine. Just connect it to 12V and it buzzes. It's pretty loud and sounds like a dryer buzzer (to me). It was loud enough that I would have wanted to bury it under the dash (might have been loud in an enclosed cab of the car), but not so loud I was concerned about it.

very loud, used it for low air buzzer on bus, worked about 1 month then it failed, hoped to get warranty on it

Needed a replacement buzzer for Mustang 940 Skid Loader when the old one shorted out and disabled the air intake grid heater making it hard to start the diesel engine in cold weather.

Much more attention grabbing than stock FOMOCO buzzer! Quality piece!
