Works fine from me. For those of you having trouble getting it to work, remember that you must drive this with an alternating current, e.g. PWM. You cannot just hook up 5v dc and get a tone.

Two of the four beepers came apart. I had to carefully super glue them back together. The sound is weak, but good enough for my purpose. They all work when connected to an Arduino. Took over 4 weeks to arrive in the USA. Pins on one poked outside of envelope. Others were bent.

I tried to use this on my Naze32 with no luck. Can't get a beep. Tested the board with a different type of buzzer and it worked. I don't think these were designed to work with RC flight controllers.
