Vorneweg, clear the thing does not cost much, so I do not expect a volume control and other bells and whistles. But I got the part bought because here it is was very loud. Who said it, I clearly too low, I'm very quick and one hears nothing. Otherwise, it's ok. For people with the appropriate drive safely 20kmh. But it's not loud and the sound is not good defenitiv. But you have to look at the price and say that it really is OK for that.
