MOOERRedkid Guitar Talk Wah Pedal

While I love the idea of having a talk-wah on my pedalboard, I have ordered this twice now and it still does not work. I have tried different 9v power sources, as well as different line cables both to my amp and my guitar from the Redkid but still it did not work. It would be a very cool pedal I bet if the product would actually work.
