They fit my students perfectly. They used them to make a series connection with a battery, a wire, a little lightbulb and this little buzzer. All worked perfectly and the campaign was crowned with success.

Cons
  • Big and chunky

Works well with horns and sirens

I bought these for a project in my class of kids to make morse code boards. All were functional. Although one didn't last long. So you're not sure if they're empty or how many times you could use them. But overall they were ok.

Pros
  • Operating Voltage: 3-24 VDC; Rated Voltage: 12VDC; Maximum rated current: 12mA; Minimum Audio Output: 85dB, Frequency Response: 3300 +/- 500Hz.
Cons
  • weak

Pros
  • Electronic buzzer Diameter Height: about 22mm*10mm; High quality and durable materials match your devices and convenient to use.
Cons
  • Expensive
