Great little active beepers
Tiny and easy to solder to board or wires. Loudness obviously depends upon voltage with 5v being the highest rated for around 85db.
Great for project
Fun little beepers. Works as described. Great for STEM project.
Easy to use, install. Pretty loud for the size.
No problem, all worked just as they should have, and price was good too.
Nice and loud - can be plugged directly in to an Uno - no jumper
It's loud, and the pins are perfectly spaced so you can plug it directly in to pin 11 and ground on an Uno - you cover a few pins but if you have a small project that shouldn't be an issue.
Good value and function
These Work great for my drone. It's loud, runs on 5V and does the job for a low price.
Worked as expected. Loud enough to use as an alarm.
Worth the money
So far they all work and they are LOUD. Much louder than the ones I was using before. That's beneficial in my case, but depending on your project they might be too loud.
