Review: Nice Buzzer - I wanted a better sound for the key buzzer for my AW11 MR2. This offers a much better and more modern sound, and was easy to integrate into the buzzer box. It felt well made and was easy to solder in place. Much better than before!
Review: Good sound even at 3V - I used one of these to make a long-reach continuity tester. With 5 or 6 meters of 22 AWG wire and associated resistance, I figured it would take something in the middle of the rated 3V to 24V range. However, I started with a 3V coin cell battery, and got a nice clear sound, plenty loud enough for the application. (Can't imagine what an ear-piercer it would be at 24V.) It emits a beeeeeeeeeeep with no buzzer-ish sound. Didn't measure the pitch.

## Questions & Answers

**Q: Will this work in a school experiment with a D battery as the power source to make the buzzer go off when the circuit is complete?**
A: I didn't have a D battery handy, but, It did work on a AA 1.5v battery. So, I would think it would work fine on your D battery. I use these as a circuit tester, for when I cant see my test light or meter on 12 volt systems.

**Q: The description somewhat confusing; Is tone one long beep....... or is it beep, beep, beep, etc?**
A: It's a continuous high pitched "beep" noise as long as voltage is applied.  Very similar tone to the backup beepers in vehicles. It does not pulse on and off unless you control the voltage on and off.

**Q: appropriate for a classroom lab?**
A: Should work very well in teaching situation

**Q: Are they waterproof?**
A: They are not waterproof.
