    Definitely loudest of small active buzzers which came in my hands until now. It have several activation possibilities - connecting to positive voltage rail, to ground or to RX PWM channel signal. From my current experience it may be heard more than 30 meters away so it is very useful of as alarm signal for small RC models such as quadcopters or cars to help find them in grass or other hidden places. At model configuration sound hole must be muted with something to avoid becoming deaf. Take in account that this buzzer will need separate +5V power, so 3 wires instead of usual two. On other side it will allow easier connection of separate battery for alarm buzzer. It is slightly larger than usual round active 5V buzzers and have naked circuit at back side. Is recommended to put it in heat sleeve and plan it location carefully to avoid space issues. It should be noted that in some occasions buzzer membrane may stuck and buzzer will become less loud - it will sound at usual small active buzzer loudness. This may happen even if buzzer is not moving.

    Very loud beeper, you can hear very well. But already the second at me ceases to squeak (wheeze, hiss) after some time of use. This is the third beeper ... With the first two problems, they ceased to squeak loudly.
