Worked good about a month and a half, witch equals using it 5 times, and the volume input potentiometer is no good, scratchy and is missing the last quarter of action. So the whole device is useless because of the input volume potentiometer doesn't work correctly and you can't get a good volume because of the last quarter of knob doesn't work and just cuts out. Extremely unhappy it breaks just after return period. So another paper weight off Amazon :( Not worth the risk, but something that's not a paperweight.
Buttons take a lot of pushing to engage. There is a terrible buzz on the input, so I couldn't even test it. This buzz is not a ground loop. I am running it on batteries. Seller claimed that this is functioning. That is an exaggeration.
