When reviewing a product like this, one has to keep the question in mind... "What did I expect for a pedal this cheap?"
It's overall good considering it is really bottom-of-the-barrel price wise. It sounds like what it is trying to be. It is also made of dirt cheap materials, and I could easily imagine it breaking by simply looking at it wrong.
It's in the lowest price range of pedals, I bought it just to get a different sound at home, so more or less as a toy. I don't need to say that if you're looking to use it for gigging, or anything involving regularly moving it, you should get something not made of cheap plastic.
