In short, I have to always be a little vorsichichtig. The bell is so loud that pedestrians when you are already too close, being duly scare. The knob of the bell can be adjusted easily, the sound is really loud and penetrating. The mechanical quality of the bell is significantly higher than that of similar products hardware store (the one sometimes already falling apart in his hand). The bell is on my bike in use for years, and I've just ordered a second for these bell's new bike. Clear, unobstructed buy recommendation.
