    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:

    Those device are easy to use with Arduino. They are cheap, and can play melodies, or make alarm noise.

    Cons:

    As it needs 9V, sound is pretty weak using Arduino. They are really small and do not provides a clear sound.

    OtherThoughts:

    Consider to add power on them when using with Arduino, as 5V DC is not enough to let it play clearly.
    I used them as a feedback "bip" to valid pressing on buttons on Arduino. I did not find more uses right now.

    Bottomline:

    If you are looking for cheap sound makers, it could be fine for you.
