Works good
Great little set to add to the collection of small electrical parts for Arduinos. Tested out on a quick little circuit and work as expected. My daughter has been annoying me with buzzers for over a day now.

More of a beeper than a buzzer.
These are really cheap and lightweight. They're as simple and inexpensive as they could possibly be. Just two thin tiny wires and a little plastic circle box. Basically weightless. You get six of them. Calling them a buzzer is pretty much inaccurate though, because the sound they make is a high-pitched beep. It's actually pretty annoying, but they work super well. You can use virtually any battery to power them, so they're incredibly easy to set up/operate and they're super versatile.
