    Overall: 5 out of 5

    I have used these buzzers for years in an engineering event with Girl Scouts and they are always dependable and loud! My only issue is occasionally they are on backorder.

    Good product

    Overall: 5 out of 5

    This buzzer creates a very loud high pitched sound that is easy to hear when you are in another room. Constructed out of good quality material.
