IT works fine, there are 3 connectors, +, - AND some kind of signal, based on the tension on this last one IT emits a different frequency. Standart connectors distance and very good price. Good loud, came with an little strip to close the sound exit, you must to remove it.
Like other arduino products should be with some kind of target naming the connectors this will make easyer to integrate this components in the project
No one at all
