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

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

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

    Amazing. Declared functional from 3 to 24 V. It emits a continuous sound. Small in size. The sound volume is excellent and increases as a function of the supply voltage. At 12 V it consumes about 10mA, at 18 V it consumes about 20mA, at 24 V it consumes about 30mA.

    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.

    and when on 5V it sounds like regular buzzer which is already not so great since it is very big compared to 5V piezzo buzzer. I did not find a SAFE way how to use it on my Flip32+ board, people suggest hooking up negative into the board (which is 5V) and positive into main battery (12V) but was told by many this could fry the board sooner or later. For other applications I am sure it will work just great....

    I used this with a ZMR250 quadcopter on a Naze32 board. I connected to the board directly and was loud but not that loud. Connect the positive to the main battery supply directly and then just connect the negative/ground to the Naze32 board and it is MUCH louder than normal which is great.

    La he cogido para mis proyectos con arduino. Suena bastante fuerte, no se si llega a los 95dB pero como alarma te enteras seguro.
