its pretty loud. if the beeper is going in a plane you better face the speakers out an opening or something, otherwise you will not hear it. its a good buy, cant fly without it.

Make sure the ground line (black one ) lines up to the correct pins. I am sure you have lined the correct wire up but I have even forgot that before. They are really cheap so manufactures do have a failure rate. You might have just blown a diode or something cheap. I would advise buy another one. Well why not just buy couple more as they are so useful. I have one on every model I fly. They are so loud and even though they are cheap they do save your model from going into a no power landing. Good Luck

4 Stück gekauft, wurden vom Zoll beschlagnahmt weil das CE-Zeichen fehlt. HobbyKing leistet keinen Ersatz und fühlt sich nicht zuständig.

I love this smal alarm system. Easy to fit and very safe. After connetion, it check every cell of your Lipo and the horn will be activated for a second. It is very loud and a nice working tool for more saftey.
