Banggood

Increíble. Declarado funcional de 3 a 24 V. Emite un sonido continuo. Pequeño en tamaño. El volumen de sonido es excelente y aumenta en función de la tensión de alimentación. A 12 V consume unos 10mA, a 18 V consume unos 20mA, a 24 V consume unos 30mA.

The item is good, the packaging is not so much. Ordered two, as can be seen in the attached photos - one arrived broken unfortunately :(

Big and loud buzzer, but direct connect to FC is quiet, you need to make a scheme for direct connect buzzer to the battery.

Come da descrizione, a 5V il suono non è molto forte.

ممتازة جدا

Il buzzer funziona ed è potente, quasi ti spacca le orecchie se sei vicino però è un pò troppo grande come dimensioni, forse sarebbe più indicato installarlo su un wing. Sono comunque soddisfatto del prodotto.

so far so good.

Unusually big one. Installed it on my Wizard X220. Really loud on 4s. But on 5v flight controller output it has rather usual volume level.

These are louder than the small ones that slot into a breadboard but you probably won't hear it in the next room.

The item was received 10 days after ordering which is good. Item was correctly packaged and looks ok.
