The housing is surprisingly sturdy in comparison with other Behringer pedals: this wah is definitely well built and reliable. But the sound just falls short of what you expect: there is practically no sweep at all, so you can't get low "oow"s and high "aah"s on the same setting. Still, this pedal is very reasonable for its price.
Not a great wah sound (which doesn't make it necessarily bad), but a really great value. It is a nicely built pedal and I ended up using it very little as a wah pedal and a whole lot as an expression pedal.
