Customer Reviews

  1. Review by Chris verified purchaser

    I used this for a VU meter project. Worked well, except (even with adjusting the potentiometer) I found it a bit too sensitive. I found that running it through a 220 resistor fixed the problem. (Posted on 10/04/2017)

  2. Review by benster - Works sufficiently for the money

    Its not as sensitive as I hoped it would be. Requires loud sounds to set off. Pot does make it more or less sensitive but it still needs a clean sound. Would work well for loud triggers.

    Otherwise, it does its job as described, (Posted on 13/05/2013)
