Simple buzzer, works perfectly
Murph from Central IL
I was surprised how hard it was to find a simple buzzer like this that did not involve other circuit components. My goal was to create a basic continuity testing device.

Just what I wanted and expected. Much more audible that what I was using.

Hooked to a dual AA battery pack, work great as part of a 4th grader invention fair project
Gary Rudnick from New Haven, CT, USA
I'm making a little electricity experimentation kit for my granddaughter and this buzzer is perfect for my needs. It's not too loud. The buzzer tone, however, seems to be voltage-dependent. This could be a good or a bad thing depending on your needs.

Buzzer works great. It is directional so helpful in understanding circuits
Nice low voltage buzzer
