Good quality but for a piece of plastic is not really cheap ....

Nice that the whistle sounds the same regardless of the weather, it is virtually rot and dirt is to wash it off. We have ordered two. Actually, we wanted to offer both models in a neon green and neon orange one in, but somehow seems not a dealer. When we have to take two neon green. In both we found the edge by producing arise (ridges) as partly disturbing and sharp-edged. The pipe itself is pretty loud but still pleasant.
But why a piece of plastic has to be partly so expensive is beyond me.
Conclusion: Good quality (sound, color) with slight defects (burrs).
Still BUY recommendation.
